fix(config): propagate Lang across credential boundary; respect CurrentApp in priorLang (#1157)

Two issues caught in review of #1132 that the existing tests missed because
they constructed RuntimeContext/CliConfig directly, bypassing the credential
edge where the bug lives.

P1 — Lang dropped at credential boundary
  credential.Account had no Lang field, so AccountFromCliConfig and
  ToCliConfig silently dropped cfg.Lang. The production Factory builds
  CliConfig via acct.ToCliConfig() (factory_default.go Phase 3), which
  meant RuntimeContext.Lang() always returned "" in production and
  shortcuts/mail/mail_signature.go always fell back to zh_cn — defeating
  the whole point of persisting --lang.

  Fix: add Lang i18n.Lang to Account and copy it in both directions.

  Regression test: TestFullChain_LangSurvivesProductionPath walks the
  real path (SaveMultiAppConfig -> DefaultAccountProvider.ResolveAccount
  -> ToCliConfig) and asserts Lang survives, so any future field added
  to CliConfig forces the same audit.

P2 — priorLang ignored CurrentApp in multi-profile workspaces
  priorLang scanned all Apps and returned the first non-empty Lang. If a
  user had multiple profiles and the active one disagreed with Apps[0],
  a re-bind without --lang would silently inherit the wrong profile's
  preference.

  Fix: read multi.CurrentAppConfig("").Lang instead.

  Regression tests cover CurrentApp wins over Apps[0], single-app
  fallback, and malformed bytes.
