Stage 8: UI social/account/history surfaces
Wire the deferred Stage 7 surfaces end-to-end (UI -> gateway transcode ->
backend REST -> existing domain services): friends (incl. one-time friend
codes), per-user blocks, friend-game invitations, profile editing + email
binding, the statistics screen, and the in-game history + GCG export.

Friends gain two add paths (interview decision, a deliberate plan change):
one-time 6-digit codes (friend_codes table, 12h TTL, single-use, rate-limited
redeem); and play-gated requests (shared game required) where an explicit
decline is permanent, an ignored request lapses after 30 days, and a code
bypasses a decline. Migration 00006 widens friendships_status_chk and adds
friend_codes.

Lobby notification badge is poll + push: a new generic `notify` event drives
it live; the client polls on open/focus. Language stays a single Settings
control that writes through to the durable account's preferred_language. GCG
export is finished-only (game.ErrGameActive) and shares/downloads the .gcg file.

Tests: backend unit + inttest (friend gate/decline/code, ListInvitations,
GetStats, GCG gate), gateway transcode round-trips + notify constructor, UI
vitest (codecs, win-rate, share choice) + Playwright social specs. Docs: PLAN
(Stage 8 done + refinements + TODO-5), ARCHITECTURE, FUNCTIONAL(+ru), UI_DESIGN,
TESTING, module READMEs.

-- +goose Up
-- Stage 8 social UI: two changes to the friend graph.
--
-- 1. A declined friend request is now remembered permanently (status 'declined')
-- instead of deleting the row, so a recipient's explicit "no" blocks the same
-- requester from re-sending (anti-spam). An ignored request still lazily
-- expires (30 days, computed from created_at in Go) and can then be re-sent; a
-- one-time friend code from the same person bypasses a prior decline. This
-- widens friendships_status_chk; the Stage 4 "declining deletes the row" rule
-- is superseded (cancelling by the requester still deletes).
--
-- 2. friend_codes backs the code-redeem add-a-friend path: the player who wants to
-- be added issues a one-time 6-digit numeric code; whoever enters it becomes
-- their friend immediately. Only the hex-encoded SHA-256 of the code is stored
-- (the plaintext is never persisted, matching the session and email-code
-- models); expires_at bounds the 12h TTL and consumed_at marks single use. At
-- most one live code exists per issuer (issuing a new one clears the prior
-- unconsumed code, enforced in Go). This adds a table, so the generated jet code
-- is regenerated (cmd/jetgen).
