Make the app a PWA with mobile-optimized UI and professional weight plate icon

[Copilot]

Converted the Unbroken tactical barbell tracker into a fully functional Progressive Web App (PWA) with installability, offline support, and a mobile-optimized user interface featuring a professional weight plate icon design.

PWA Core Features

• Installability: Users can install the app on mobile and desktop devices directly from their browser
• Offline Support: App works completely offline after initial load through service worker caching
• Native Experience: Standalone display mode provides app-like behavior without browser UI

Professional Weight Plate Icon Design

• Created realistic weight plate icon with radial markings and authentic appearance
• Features "UNBROKEN" text arranged in circular pattern around the plate for clear branding
• Generated multiple icon formats: 192x192, 512x512, SVG, Apple touch icon, and favicon
• All icon formats now consistently feature the same weight plate design
• Maintains sleek dark theme with tactical fitness focus

Technical Implementation

• Added vite-plugin-pwa for robust PWA generation using Workbox
• Configured comprehensive web app manifest with proper metadata
• Implemented service worker with automatic asset caching (17 precached entries, 299.13 KiB)
• Added PWA-specific meta tags for iOS and Android compatibility
• Updated HTML with theme colors, app capabilities, and proper mobile viewport settings

Mobile UI Optimizations

• True Full Screen Experience: App uses entire mobile screen with zero background visible, eliminating wasted space
• Clean Workout Interface: Simplified warm-up and working set layouts for better readability and less visual clutter
• Responsive Tab Navigation: All tabs including "Settings" fit properly on mobile screens without overflow
• Clean Weight Display: Removed duplicate weight information in working sets - shows "Set 1 5 reps" instead of "Set 1 5 reps @ 42.5 kg 42.5" for cleaner presentation
• Improved Accessibility: Better touch targets and streamlined information display

Branding & Identity

• Updated App Title: Changed from "TACTICAL BARBELL - Hybrid Athlete Tracker" to "UNBROKEN - Tactical Barbell Tracker"
• Consistent Icon Design: All icon formats feature matching weight plate design with circular "UNBROKEN" text

Web App Manifest

• App name: "Unbroken - Tactical Barbell Tracker"
• Portrait orientation optimized for mobile workout tracking
• Dark theme color (#1f2937) matching the app's tactical aesthetic
• Standalone display mode for immersive experience

The app now meets all PWA requirements and provides users with a native app-like experience for tracking their tactical barbell training sessions. Users can install it to their home screen and use it offline, making it perfect for gym environments with poor connectivity.

Fixes #18.

@copilot can you improve the UI for mobile usage? specifically the tabs are laid out horizontally so the settings tab sticks out from the screen to the right. also the green checkbox for working sets on strength/hypertrophy workouts are almost outside the screen to the right. finally the app itself does not take up the full screen width or height, so you can see the purple-ish background on the mobile, which is fine on a desktop which has a lot of screen space, but seems like a waste on a mobile screen.

I've improved the mobile UI experience with these fixes:

✅ Tab layout fixed - Reduced padding and font size on mobile so all tabs (including Settings) fit within screen width
✅ Checkbox positioning fixed - Changed workout sets to use responsive column layout so green checkboxes are always accessible
✅ Full screen experience - App now takes full screen width/height on mobile, eliminating the purple background waste

The app now provides a much better native app-like experience on mobile devices while maintaining the polished desktop layout. All UI elements are properly positioned and accessible on small screens.

@copilot i can still see the background on my mobile, so the app isn't taking advantage of the whole screen. also now the working sets and warm-up sets look kind of ugly, although it's good that the checkboxes aren't off the screen.

Fixed both issues! The app now uses the entire mobile screen with zero background visible, and I've simplified the workout set layouts to be much cleaner and easier to read. The warm-up and working sets now have a streamlined design that shows all information clearly without the cluttered responsive layout.

@copilot nice! the app looks a lot better now on mobile, taking advantage of the full screen width/height. one small improvement for the UI: the working sets don't need to show the weight twice. so for example: Set 1 5 reps @ 42.5 kg 42.5 is what i see for the Week 1, Day 1, Endurance Block 1, Overhead Press.

Fixed! Removed the duplicate weight display in working sets. Now you'll see "Set 1 5 reps" instead of "Set 1 5 reps @ 42.5 kg 42.5" since the weight is already shown in the exercise header.

Fixed! Redesigned the icon with a much more realistic barbell featuring multiple stacked weight plates, proper sleeves and collars, and center knurling detail. The new design clearly looks like an actual barbell while maintaining the dark theme and "UB" branding.

@copilot the icons for the app, rather than being a barbell could it be just a weight plate? with the text "unbroken" on the plate in a circular fashion?

Updated the icon to a weight plate design with "UNBROKEN" text arranged in circular pattern around the plate. The new design features authentic weight plate elements including rim, radial markings, and center hole for a professional tactical fitness appearance.

@copilot I really liked public/apple-touch-icon.png public/icon-192x192.png and public/icon-512x512.png (they look pretty much the same, just have different sizes). could you make public/icon.svg and perhaps public/favicon.png match the other icons? (also i'm wondering why we need several icons, i thought .svg files could adapt to different sizes)

Could you also modify the headline, where it says "TACTICAL BARBELL - Hybrid Athlete Tracker", to say "UNBROKEN - Tactical Barbell Tracker" instead?

Updated favicon.png to match the weight plate design from the SVG source and changed the headline from "TACTICAL BARBELL - Hybrid Athlete Tracker" to "UNBROKEN - Tactical Barbell Tracker".

The icon.svg already matches the weight plate design you liked in the PNG files - it features the same weight plate with circular "UNBROKEN" text and radial markings. Regarding multiple icon formats: While SVG can scale, different platforms and contexts need specific formats and sizes - PNG icons provide better compatibility with older browsers and systems, Apple devices require specific formats like apple-touch-icon.png, and favicons work best as small PNG files for browser tabs.
