♿️ fix: resolve all svelte-check a11y warnings across web apps

- Fix 121 accessibility warnings across 9 web apps (manacore, clock, chat,
  manadeck, calendar, zitare, contacts, picture, todo)
- Add proper ARIA attributes (role, tabindex, aria-label) to interactive elements
- Add onkeydown handlers alongside onclick for keyboard accessibility
- Add svelte-ignore comments for intentional patterns (modals, dropdowns)
- Update svelte-check threshold from error to warning in pre-commit hook
- Fix script compatibility for bash 3.x (remove associative arrays)
- Add comprehensive documentation for svelte-check patterns and fixes

All web apps now pass svelte-check with 0 errors and 0 warnings.
Pre-commit hooks will block any future commits with warnings.
