perf(css): reduce generated global CSS for #235

[hrx01-dev]

Summary

• narrow Tailwind v4 source scanning to runtime source trees instead of the broad src/** glob
• avoid scanning tests/non-runtime files that can contribute unused utilities
• keep all runtime app, admin, dashboard, Firebase, and entrypoint sources covered

Issue

Closes #235

Validation

The repository's existing CI/build and bundle-budget workflows should validate the generated CSS size and runtime coverage.

Summary by CodeRabbit

• Bug Fixes
  • Improved styling build accuracy by limiting source scanning to active application files.
  • Prevented test and other non-runtime files from affecting generated styles.
