feat: LUKS2 encryption, boot sequence fixes, onboarding auth, CI/CD

- LUKS2 full-partition encryption for /var/lib/archipelago/ (TASK-42)
  4-partition layout: BIOS + EFI + root (30GB) + encrypted data
  AES-256-XTS with AES-NI detection, ChaCha20 fallback for ARM
  Auto-unlock via crypttab + random key file

- Fix EFI boot errors: remove shim-signed, clean shim artifacts
- Fix first-boot sequence: always show boot animation before onboarding
- Fix stale localStorage causing login instead of onboarding (BUG-47)

- Add auth.setup + auth.isSetup RPC handlers for password on clean install
- Add onboarding methods to UNAUTHENTICATED_METHODS (DID sign 403 fix)

- FileBrowser bundled in unbundled ISO, fix auto-login Secure cookie (BUG-46)
- Kiosk mode: xorg/chromium in rootfs, toggle script, MOTD instructions

- Add Gitea Actions CI/CD workflow for automatic ISO builds

+### BUG-46: FileBrowser missing in unbundled ISO + Cloud auto-login broken (IN PROGRESS)
+**Priority**: P1 — High
+**Status**: IN PROGRESS (2026-03-26)
+
+Two issues with the Cloud feature on fresh installs:
+
+1. **FileBrowser not prepackaged in unbundled ISO** — The unbundled ISO variant doesn't include the FileBrowser container image, so Cloud doesn't work out of the box. FileBrowser is a core dependency (not an optional app) since it powers the Cloud file manager. Must be bundled even in the unbundled variant.
+
+2. **FileBrowser auto-login not working** — The auto-login flow (so users don't need to enter separate FileBrowser credentials) appears broken. Need to investigate whether the auth proxy/token injection is functioning correctly on fresh installs.
+
+**Tasks**:
+- [x] Add FileBrowser image to unbundled ISO build (core dependency, always bundled)
+- [x] Create minimal first-boot script for unbundled mode (FileBrowser only)
+- [x] Fix auto-login: `Secure` cookie flag silently fails on HTTP — made conditional
+- [x] Changed `SameSite=Strict` to `SameSite=Lax` for better navigation compatibility
+- [ ] Test Cloud feature end-to-end on a fresh install (both bundled and unbundled)
+
+**Key files**:
+- `image-recipe/build-auto-installer-iso.sh` — UNBUNDLED container image list
+- `scripts/first-boot-containers.sh` — FileBrowser container creation
+- `image-recipe/configs/nginx-archipelago.conf` — FileBrowser proxy config

+
+### BUG-47: Onboarding: DID sign 403 + blob HTTPS + no password setup (IN PROGRESS)
+**Priority**: P1 — High
+**Status**: IN PROGRESS (2026-03-26)
+
+Three onboarding issues on clean install:
+
+1. **Sign DID returns 403 Forbidden** — The DID verification/signing step during onboarding fails with a 403 response from the backend.
+2. **Blob URL HTTPS warning** — Browser complains about blob URL loaded over insecure connection (`blob:http://...` should be served over HTTPS). Likely related to the backup download on HTTP connections.
+3. **No password setup on clean install** — Users cannot set a password during onboarding. The setup password flow is missing or broken.
+
+**Root causes found**:
+- `node.did`, `node.signChallenge`, `node.nostr-pubkey`, `node.createBackup`, `identity.verify` were NOT in `UNAUTHENTICATED_METHODS` — onboarding has no session, so they all returned 403
+- `auth.setup` and `auth.isSetup` RPC methods were missing from the dispatcher — the frontend called them but no handler existed
+- Blob HTTPS warning is a browser security feature on HTTP connections (not a code bug)
+
+**Tasks**:
+- [x] Add onboarding methods to UNAUTHENTICATED_METHODS in middleware.rs
+- [x] Add `auth.setup` RPC handler (creates user with password, prevents re-setup)
+- [x] Add `auth.isSetup` RPC handler (checks if user.json exists)
+- [x] Rust compiles clean
+- [ ] Blob URL HTTPS warning — known browser limitation on HTTP, no code fix needed
+- [ ] Test full onboarding flow end-to-end on fresh ISO
