Title

Add full-stack Tip Jar dApp guide using Dynamic and Foundry

Description

This PR adds a new developer guide that walks users through building a complete Tip Jar dApp on the Rootstock Testnet.
It combines smart contract deployment using the Rootstock Foundry Starter Kit and a full-featured React/Next.js frontend using the Rootstock Dynamic Kit.

NOTE: The tutorial is meant to showcase the Rootstock Dynamic Kit. Due to the fact that a contract had to be deployed, it was just easier to use the Rootstock Foundry Kit to deploy it.

Screenshots/GIFs

• send-tip.gif: Shows real-time tip flow through the UI
• deployment-output.png, forge-build-output.png: Deployment steps and build output
• contract-verification.png, withdraw-funds.png: Post-deployment actions and fund withdrawal
• Additional video walkthrough

Testing

• Verified tutorial steps end-to-end using a local dev environment
• Tested contract deployment, UI integration, and RBTC tipping
• Used yarn build to confirm no broken links or build issues after adding assets

Hi @owans , when I'm trying to fix the linting errors, the style guide forces me to use the rootstock.io domain for the RPC endpoint:

rootstock_testnet = "https://public-node.testnet.rsk.co"

I did a bit of research, and it seems that the correct endpoint is indeed the above one.

Even trying to turn off vale for that section of text is not possible because the scope is set as raw here https://github.com/rsksmart/docs-style-guide/blob/main/styles/Rootstock/601-Rootstock-domains.yml

I'm also getting a warning from https://github.com/rsksmart/docs-style-guide/blob/main/styles/Rootstock/016-No-inline-comments.yml every time I use code blocks like bash or toml, even when there are no comments inside. The rule might be too strict because it uses scope: raw and tries to match full code blocks, which causes false positives.
