feat(nip46): security-icon trust picker + reconnect affordance

Two of the three refinements from the Primal comparison:

Trust picker as security icons: unify the connect dialog and the app-detail
picker on one open→shield→locked glyph set — LockOpen (Full trust, never asks),
Shield (Reasonable), Lock (Paranoid) — replacing the connect dialog's emoji and
the detail's heart so both surfaces read the same and the icon carries the
guard-level at a glance.

Reconnect affordance: when an app's relays show Offline (from the live status
added last commit), offer a one-tap Reconnect — on the connected-apps row and in
the detail's Relays section — that forces the relay pool to re-dial now, ignoring
backoff. Shared Nip46ReconnectPill.
