chore(#251): codebase cleanup — dead files, stale docs, wrong paths

[ChristopherRotnes]

Summary

• Closes As a developer I want the codebase and docs cleaned up so I can work from a clear, accurate baseline #251

Dead files deleted

• Bibliotek.jsx — retired since v1.4.0, zero imports
• OvelseDetail.jsx — never imported anywhere, superseded by inline ExerciseForm editing

README.md

• Removed Bibliotek.jsx entry from project structure table
• Fixed ExerciseRow.jsx description — no longer mentions sets/reps (removed in v1.5.0)
• Fixed wrong paths: carbon-tokens.css and app.css are in app/src/styles/, not app/public/styles/
• Fixed staticwebapp.config.json — lives at app/public/staticwebapp.config.json, not app/staticwebapp.config.json

CLAUDE.md

• Replaced "What was done" Carbon migration narrative with current-state description
• Removed Bibliotek.jsx RETIRED entry
• Removed History.jsx / MonthGrid.jsx bullet (its only content was "removed react-day-picker" — historical noise)
• Removed "Removed: Bebas Neue, DM Sans..." bullet
• Trimmed i18n line — replaced "date-fns has been removed entirely" with prescriptive instruction
• Trimmed sets/reps note — stated as current fact, not history
• Trimmed gym-wide templates section — removed RLS old/new policy diff and db.js change list; kept the FK constraint warning which is still actionable
• Fixed ExerciseRow.jsx component description — removed stale "sets/reps inputs"
• Fixed ExerciseForm.jsx — removed "Extracted from inline definition in Bibliotek.jsx"
• Fixed API security bullet — now correctly documents X-Supabase-Token (was incorrectly stating Authorization: Bearer)
• Cleaned up template navigation — removed "(was onShowBibliotek)"

app/package.json

• Bumped version from stale 1.1.0-rc.1 to 1.5.10

Test plan

• Lint passes (no imports of deleted files)
• No remaining references to OvelseDetail or Bibliotek in source
