thePR0M3TH3ANandClaude Opus 4.8 0db4f0a603 perf(subscriptions): cut redundant cold-login list fetches
Two redundancies were inflating the login REQ burst (kind 30000=19 storm in
the real-env console — the cause of the slow hashtags, KNOWN_BUGS #0),
isolated with the channel-sim harness's REQ-signature + timing capture:

1. Duplicate trigger: ProfileModalController.handleAuthLogin called
   subscriptions.loadSubscriptions() AND userBlocks.loadBlocks() DIRECTLY at
   login, on top of the auth coordinator's gated list loads — a second,
   ungated relay round-trip for each. Route them through ensureLoaded()
   instead so they coalesce with the coordinator's in-flight load. Harness:
   subscriptions updateFromRelays now fires ONCE at login instead of 3×
   (≈3× fewer kind-30000 fetches in prod, where each is multiplied by the
   relay set).

2. Fetch/decrypt coupling: a decrypt retry re-ran the full relay fetch even
   though only signer availability had changed. Cache the fetched ciphertext
   (_pendingDecryptEvent) and have scheduleDecryptRetry re-decrypt it via a
   cachedDecryptEvent fast-path in updateFromRelays — no redundant relay
   query per retry.

Validated: MODE=overload (channel drops) still decrypts blocks +
subscriptions + hashtags (DMs OK); full unit suite green; subscription loop
+ aggregation tests still pass.
