refactor: remove exactOptionalPropertyTypes and fix import casing

Phase 1: Configuration Fix
- Remove exactOptionalPropertyTypes from tsconfig.json
  This strict option caused 22+ incompatibilities with third-party libraries
  (bits-ui, wx-svelte-grid) without providing sufficient value
- Fix Switch.svelte import casing in settings page
  Changed from 'switch/switch.svelte' to 'switch/Switch.svelte'

Result: 53 → 45 errors (8 errors fixed)
