refactor: remove dead code surfaced by fallow (Phase 1)

- Delete 13 unused files: Vite-starter icon components, an
  orphan footer layout, two abandoned CTS pages, a refactor-
  leftover percent-edit dialog, two unused photo-gallery
  variants, and CSS assets with zero imports.
- Drop @quasar/extras and @pinia/testing from package.json
  after verifying zero usages. Future SVG-icon migration is
  tracked separately in PLAN-svg.md.
- Remove unused exports (and the now-dead local declarations
  that supported them) from colors.ts, DateFunctions.ts,
  QuasarConfig.ts, photo-gallery-service.ts, use-percentage-
  form.ts, error-transformer.ts, permission-messages.ts, and
  schedule-config.ts. colors.ts in particular collapses from
  256 lines to 31 after the dead palette plumbing is removed.
- Fallow's `percentRule` and SCHEDULE_LABELS/SCHEDULE_MESSAGES
  findings are false positives (direct imports and dynamic
  imports fallow missed) — kept as-is.
