Add dark: variants for the green success banner on the account page
so it doesn't appear overly bright against the dark background.
Also tidy .gitignore to catch all .db and .db-journal files.
Move CSS, JS, favicon files to static/ directory to separate
compiled-in assets from Askama templates. Update all include paths,
build.rs, flake.nix, and Tailwind @source directives.
Replace the checked-in styles.css with a build-time Tailwind CSS
pipeline. input.css defines CSS custom properties for light/dark
themes, mapped to Tailwind utilities via @theme. build.rs runs
the Tailwind CLI to generate styles.css at compile time.
Add dotenvy::dotenv() call before CLI argument parsing so that
environment variables (e.g. API keys) can be set in a .env file
instead of the shell environment. Add .env to .gitignore.
- Add BackupData struct and BackupService with raw SQL export/import
- Restore uses raw inserts to bypass brew deductions and timeline creation
