Tests were written against the pre-Stream B flat settings page. After
the left-nav restructure (bd6a301) and the management-surfaces revamp,
the Display section's IDs are only in the DOM once the user navigates
there, and renderSettings makes additional sendMessage calls (is_unlocked,
per-section data) that the original mocks didn't cover.

Closes three audit gaps in one pass:
1. Sync now button in the popup settings view (📤). Triggers the existing
{ type: 'sync' } SW message and surfaces success / failure inline. The
SW message was already wired but had no UI entry point.
2. Device registration from the popup. The "Register this device" button
on the devices view used to error out with a "not yet implemented"
message; it now opens an inline name input (default = browser+OS), and
on confirm sends a new register_this_device SW message that generates
an ed25519 keypair via WASM, persists private_key + name to
chrome.storage.local, and writes the public key to the remote
devices.json. No setup-wizard detour.
3. Vault tab is now an authorized sender for popup-only SW messages. The
router accepts vault.html alongside popup.html, so the fullscreen tab
can drive the same flows. Test covers acceptance from the vault tab.
New SW message: register_this_device { name }. Added to PopupMessage and
POPUP_ONLY_TYPES, handled in router/popup-only.ts.
Tests: 5 new vitest cases (3 in settings.test.ts, 2 in devices.test.ts)
+ 1 router test for vault-tab acceptance. All 194 extension tests pass.
