fix: UEFI ESP partition type, WebSocket cookie, password UX

UEFI boot:
- xorriso now uses -append_partition with ESP type GUID
  (C12A7328-F81F-11D2-BA4B-00A0C93EC93B) instead of -isohybrid-gpt-basdat
  which only creates "basic data" partitions. Strict UEFI firmware
  requires the correct ESP type to find BOOTX64.EFI.
- Uses Arch Linux ISO approach: -append_partition + appended_part_as_gpt

WebSocket/login from LAN browser:
- HTTPS nginx /ws block was missing proxy_set_header Cookie $http_cookie
  Session cookie wasn't forwarded → backend returned 401 → WS failed

Password UX:
- Renamed "Change Password" → "Set Password" with description explaining
  default password is password123
