release(v1.7.10-alpha): apply namespace fix + FIPS cascade + profile polish
Some checks failed
Build Archipelago ISO (dev) / build-iso (push) Has been cancelled
Details

Browse Source 
THE apply fix
  archipelago.service uses ProtectSystem=strict, so /opt and /usr are
  read-only inside the service's mount namespace. sudo inherits that
  namespace — every sudo mkdir/mv/chown from apply_update was hitting
  EROFS even as root. Every prior "Failed to apply update" was a
  symptom of this. New `host_sudo()` helper wraps every filesystem
  call in `sudo systemd-run --wait --collect --pipe -- <cmd>`, which
  spawns a transient unit with systemd's default (no ProtectSystem)
  protections — the command runs in the host namespace and can touch
  /opt/archipelago + /usr/local/bin normally.

FIPS cascade (#2)
  Home.vue and Server.vue both carry a FIPS row that previously only
  looked at {installed, service_active, key_present}. Now they also
  read anchor_connected + authenticated_peer_count and mirror the
  full FIPS card: green "Active · N peers" when healthy, orange "No
  anchor" when the DHT bootstrap has failed.

Profile paste URL fallback (#4)
  Web5Identities.vue list + editor previously had `@error="display:none"`
  on the <img>, which hid the tag without re-rendering the fallback —
  a broken pasted URL showed up blank. Replaced with reactive
  pictureLoadFailed / listPictureFailed flags plus a watcher that
  resets on URL change. Broken URL now falls back to the initial (or
  identicon for seed-derived identities).

Small-upload data URL (#3)
  Uploaded profile pictures ≤ 64 KB are now inlined as
  `data:image/png;base64,...` into profile.picture on the client
  before calling update-profile. That kind-0 event is fetchable by
  any Nostr client — no Tor needed. Larger uploads fall back to the
  onion-rooted public_url with a hint telling the user to paste a
  public https:// URL for broader visibility.

Deferred: #1 FIPS Reconnect "actually fixes" — the current Reconnect
calls fips.restart which clears the daemon state, but when the
anchor is truly unreachable (UDP 8668 blocked by network/ISP), no
amount of restart can help. A richer diagnostic is out of scope for
this bundle.
