Relay tab improvements so users can see which relays to remove:
- Per-relay status pill: Online (with ping) / Offline / Checking… / Blocked.
- Insecure remote ws:// relays (CSP-blocked) flagged immediately with a hint.
- Offline relays show a "consider removing" hint; their Remove button is
emphasized.
- Summary banner when relays are down (incl. the all-dead case explaining why
videos won't load), pointing at Restore defaults / healthy relays.
Also fixes a pre-existing decomposition bug (commit 7300977a): handleRelayOperation
called this.runRelayOperation, but that method lives on the main
ProfileModalController — so ALL relay ops (add/remove/mode/restore) threw
"this.runRelayOperation is not a function". Route via this.mainController.
Tests: relay-insecure-url (isInsecureRelayUrl), relay-operation-routing (routes to
mainController.runRelayOperation, guards no-pubkey). Both mutation-verified.
Build + lint + full unit suite green.
