fix(lark): hide only the Lark (international) connect entry; keep Feishu

Mainland Feishu binding works; only the newly-added Lark (international,
open.larksuite.com) install path is unreliable — some Lark installs
complete on Lark's side but never persist a lark_installation row (no WS,
no inbound, no task). Hide just the "Bind to Lark" CTA behind a single
LARK_INTL_CONNECT_ENABLED flag and leave the "Bind to Feishu" entry, the
settings panel, and all existing-installation management untouched.

Flip LARK_INTL_CONNECT_ENABLED back to true to restore the Lark CTA;
nothing else changes. Temporary measure while the Lark install-landing
bug is investigated.

- LarkAgentBindButton: the Lark button is gated by the flag; the Feishu
  button and the Connected badge / Manage / Disconnect are unchanged.
- Tests: the CTA tests assert Feishu shown + Lark hidden; the Feishu
  click-to-begin (region=feishu) test stays; the Lark click test was
  removed (no button) and noted for restore; the dialog polling-error
  tests open via the Feishu CTA.
