Fix key-file unlock link by removing translatable HTML markup

[Copilot]

In 2.7.11, the “I have a key file” action in the unlock dialog could become non-functional in some translations because the translatable string embedded HTML anchor markup. This made link activation dependent on translated HTML structure instead of stable UI code.

• Root cause correction: move markup out of translations

  • DatabaseOpenWidget.ui now stores plain text (I have a key file) instead of an HTML <a> string.
  • This removes translator-facing HTML and avoids runtime breakage from localized tag changes.

• Behavior preservation in code

  • DatabaseOpenWidget.cpp now wraps the translated plain text in anchor markup at runtime, keeping the label clickable and preserving linkActivated -> browseKeyFile.

• Security/robustness detail

  • The translated text is HTML-escaped before insertion into the anchor template.

m_ui->addKeyFileLinkLabel->setText(
    QStringLiteral("<a href=\"#\" style=\"text-decoration: underline\">%1</a>")
        .arg(tr("I have a key file").toHtmlEscaped()));
