feat: fix blank frontend page — align all page forms with backend store fields

- Add <script setup> to all 4 page components for consistent Svelte 5 syntax
- Fix field name mismatches between frontend forms and backend mock API:
  * LanPage: dhcp_enabled -> dhcp, removed non-existent subnet field
  * MainRelayPage: replaced state/name/automatic/voltage/delay with lockDelayMs/unlockDelayMs
  * ElevatorPage: replaced floors/speed_up/speed_down/max_load with enabled/timeoutMs
  * DevicePage: replaced baud_rate/scanning/devices with type/sn/name/unit/room
- Add saved state tracking and error display to all pages
- Clean up App.svelte: remove svelte onMount import, simplify navigation logic
