Fixes WCAG 2.1 AA contrast failure (#341): text-accent (#a1dcd8) on light
PDF control bar was 1.52:1 — well below the 4.5:1 AA minimum. text-primary
resolves to #012851 in light mode (14.5:1) and #a1dcd8 in dark mode (9:1) —
both states pass AA in both themes.
Adds PdfControls.svelte.spec.ts with 5 tests covering toggle visibility,
label strings, and the contrast-safe class assertion.

## Pre-commit hook
- Add .husky/pre-commit at repo root: runs `cd frontend && npm run lint`
- Update prepare script in package.json to auto-configure git hooks path
on npm install (git -C .. config core.hooksPath .husky)
- Add lint step to CI unit-tests job so it catches issues before tests run
- Add generated dirs to .prettierignore (paraglide_bak*, test-results, .auth)
- Add src/lib/paraglide_bak* to .gitignore so ESLint can ignore them
## ESLint fixes (all pre-existing)
- Disable svelte/no-navigation-without-resolve: false positive in SvelteKit
(rule targets Svelte 5 standalone routing, not SvelteKit <a href>)
- Fix svelte/require-each-key: add (item.id)/(item) keys to all {#each} blocks
across 10 files — improves Svelte reconciliation performance
- Fix svelte/prefer-writable-derived in PersonTypeahead: $state+$effect → $derived
- Fix svelte/prefer-svelte-reactivity: URLSearchParams → SvelteURLSearchParams,
Map → SvelteMap (enables Svelte reactive tracking)
- Fix @typescript-eslint/no-unused-vars: remove dead imports/variables
## Prettier
- Run npm run format to bring all source files in line with .prettierrc
