feat(fips): connect to public mesh anchor over TCP + wire daemon updates

The whole fleet was silently never reaching the FIPS mesh: the default
public anchor was configured as fips.v0l.io:8668/udp, but the anchor only
answers on TCP/8443. Fix the default to 185.18.221.160:8443/tcp (IPv4
literal — the hostname resolves IPv6-first and the daemon binds v4-only,
which fails the handshake with EAFNOSUPPORT), and auto-seed it in
anchors::load() so every node dials it without operator action (removal
still persists). Proven live on .116: cold start → anchor_connected in
~400ms, anchor became mesh parent.

Wire fips::update::apply() against upstream GitHub releases (stable
channel only): resolve /releases/latest → SHA256-verify the .deb against
checksums-linux.txt → install → restart. dpkg runs via `systemd-run` to
escape archipelago's ProtectSystem=strict sandbox (else /var/lib/dpkg is
read-only), with --force-confold (archipelago manages /etc/fips conffiles)
and --force-downgrade (dev builds sort newer than the stable tag).
Validated live: .116 upgraded 0.3.0-dev -> stable v0.3.0.

Also: standalone fips-ui dashboard app (apps/fips-ui + docker/fips-ui,
static nginx proxying /rpc/v1 same-origin, copiable own-anchor address);
reserve UI port 8336; register fips/fips-ui as platform-managed. Includes
the Lightning wallet cross-origin (CORS) + LND proxy auth + nginx
self-healer fix so the wallet screen connects instead of "failed to fetch".
