Stage 11: account linking & merge (email + Telegram Login Widget)
Link an email (confirm-code) or Telegram (web Login Widget) to the current
account; if the identity already has its own account, merge the two into the
one in use (the current account is primary, except a guest initiator whose
durable counterpart wins). The merge runs in one transaction
(internal/accountmerge): stats + hint wallet summed, paid_account ORed,
identities/games/chat/complaints transferred, friends/blocks de-duplicated,
the secondary kept as a merged_into tombstone so a shared finished game's
no-cascade FKs hold; a shared active game blocks the merge.

- migration 00009: accounts.paid_account, merged_into, merged_at (+ jetgen)
- internal/link orchestrator; session.RevokeAllForAccount on merge
- connector ValidateLoginWidget RPC + loginwidget HMAC validator
- edge ops link.email.request/confirm/merge, link.telegram.confirm/merge;
  supersedes the Stage 8 email.bind.* surface (request never reveals 'taken'
  before the code is verified, so a probe cannot enumerate addresses)
- UI Profile link section + irreversible-merge dialog; Telegram web sign-in
- focused regression tests (merge core, guest inversion, active-game refusal,
  finished-shared-game kept), gateway transcode + connector + UI codec/e2e
- docs: PLAN, ARCHITECTURE 3/4/9, FUNCTIONAL(+ru), module READMEs

-- +goose Up
-- Stage 11 account linking & merge: retire a secondary account into a primary one.
-- merged_into/merged_at turn the secondary into an audit tombstone (its identities
-- are repointed and its non-shared rows transferred to the primary, but the row is
-- kept so the no-cascade game_players/chat/complaints foreign keys of any shared
-- finished game stay valid). merged_into self-references accounts and is SET NULL on
-- delete so a future guest reaper (PLAN.md TODO-3) can still remove a primary.
-- paid_account is a forward-looking lifetime one-time-payment marker (no purchase
-- flow yet); the merge ORs it so a paid status is never lost. Adds columns, so the
-- generated jet code is regenerated (cmd/jetgen).
