chore(admin-ui): optimize eager bundle and remove unused styles (#3032)

Summary

  • Reduced the Admin UI eager critical-path bundle by removing duplicate Bootstrap CSS, unused external stylesheets, dead SCSS variants, and unnecessary eager editor code.
  • Improved support for air-gapped deployments by removing runtime dependencies on external CDN and font hosts.
  • Cleaned up unused Vite code-splitting configuration.

Results

Measured against 80cbd3113 built from a clean worktree with the same script.

Metric Before After Delta
Eager critical path (gzip) 748.4 kB 548.0 kB −200.4 kB (−27%)
Eager critical path (raw) 2933.8 kB 1939.6 kB −994.2 kB (−34%)
index.css 483.3 kB 242.8 kB −240.5 kB (−50%)
app-shared.css 101.4 kB 1.4 kB −100.0 kB (−99%)
Eager assets 17 16 −1
External CDN hosts 3 0 air-gap safe

Fix Summary

  • Removed the duplicate Bootstrap CSS import so Bootstrap is compiled and shipped only once.
  • Removed unused react-block-ui, Font Awesome, and Google Material Icons CDN stylesheet references.
  • Removed the unused Material Icons @font-face declaration from app/styles/index.css.
  • Removed dead Card and CardHeader color variant generation that cannot be produced by current call sites.
  • Removed unreachable theme color variants that cannot be produced by the current ThemeProvider configuration.
  • Moved react-ace out of the eager bundle and ensured the editor mounts without introducing layout shift.
  • Removed unused FEATURE_GROUPS entries from the Vite configuration.
  • Preserved existing light and dark theme behavior.

Verification

  • Verified Bootstrap is compiled and included only once in the production output.
  • Verified the built application has no external stylesheet/font dependencies on CDN hosts.
  • Verified unreachable CSS class combinations are no longer generated.
  • Verified react-ace is no longer part of the eager critical path.
  • Verified there are no unexpected layout shifts when the editor mounts.
  • Verified light and dark themes have no visual regressions.
  • Verified tsc passes.
  • Verified the test suite passes.
  • Verified build:prod passes.
  • Verified the production bundle using npm run preview:prod:analyze.

🔗 Ticket

Closes: #3032

Summary by CodeRabbit

  • New Features

    • Added a reusable code editor with language, theme, read-only, placeholder, sizing, and change-handling options.
    • Added an extra-wide responsive breakpoint at 1400px.
    • Added support for single-date and date-range picker experiences.
  • Improvements

    • Code editors and date pickers now load asynchronously with loading placeholders.
    • Webhook header fields no longer trigger browser autocomplete.
    • Streamlined available Bootstrap utility styles.
  • Style Updates

    • Removed color-specific card and theme variants.
    • Removed external icon and stylesheet references.

- Drops the CDN `<link>` tags and the bundled `bootstrap.css` import in favour of the local SCSS build, so the app no longer blocks first paint on three third-party stylesheets
- Prunes the Bootstrap utility API to the classes actually used and deletes the per-colour card, card-header and theme-variant loops, which generated hundreds of unused selectors
- Splits `AceEditor` and its modes/themes into `GluuAceEditor` behind `React.lazy`, so the editor bundle only loads on forms that render one
- Drops the table, dnd and floating-ui manual chunks so Rollup can group them by usage, and adds `autoComplete="off"` to the webhook header inputs

Explanation

The pull request adds lazy loading for GluuDatePicker through the new DatePickerChild.tsx and updates related date-picker tests. Issue #3032 requires eager-path changes for Bootstrap, external styles and fonts, unreachable CSS, react-ace, and unused Vite groups. It does not require lazy loading MUI date pickers. The pull request also adds two unrelated autoComplete="off" attributes in WebhookForm.tsx.

Brings in #3026 (FIDO metrics charts), #3022 (cloud-native) and #3027 (docs). No file overlaps this branch's CSS and bundle changes, so the merge applies cleanly.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Single mode with showTime gets a date-only default format.

Line 63 forces showTime to false for every non-range props object. defaultFormat then resolves to DATE_FORMATS.DATE_PICKER_DISPLAY_US. Line 91 still selects DateTimePicker or DesktopDateTimePicker from props.showTime. If a caller passes mode="single" with showTime and no dateFormat/format, the date-time picker renders with a date-only format, so the time part is not displayed and cannot be typed.

Derive showTime from props.showTime in both modes.

🐛 Proposed fix
-    const showTime = isRange ? (props.showTime ?? false) : false
+    const showTime = props.showTime ?? false
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
