release(v1.7.25-alpha): TCP transport for public FIPS mesh + modal cleanup

Re-adds the TCP transport (`0.0.0.0:8443`) to the rendered fips.yaml
alongside UDP. Upstream factory default enables both; we had
inadvertently narrowed to UDP-only when the yaml rewriter was last
touched, which left nodes unable to reach fips.v0l.io (the public
anchor only answers on TCP right now) or talk across networks that
block UDP.

Backend startup now compares the installed yaml against the current
rendered schema and restarts whichever fips unit is active when they
differ — so OTA-upgrading nodes pick up the new transport without
anyone having to click Reconnect.

Dropped the earlier plan to auto-add federated peers as seed anchors:
invites don't carry a FIPS-reachable IP:port, and once TCP reconnects
the public mesh, federated peers become npub-routable without needing
a seed entry.

Seed Anchors modal cleanup: replaced malformed header icon with a
three-arc broadcast glyph, and the close button now matches the
What's New modal (embedded in the card header, same icon + hover
style) instead of the earlier floating off-design placeholder.
