Keep every hook call's response, searchable by the user and the bot

A hook call used to record only how it was taken; its run's answer went
to the chat alone and was lost to the call once the job was pruned. Now
`bot_hook_events` keeps `response`, `response_message_id` and
`responded_at`, written on every call a run took in when that run ends
(completed, failed, lost, stopped or cancelled) by
`recordHookCallResponse` in the job helpers, and calls turn done or
failed. The Calls view searches what calls sent and what runs answered,
filters by status and pages; Show all loads one call whole. Bots get
`search_hook_calls` and `read_hook_call` for their own hooks (never in a
hook call's own run), with payloads always marked as outside data.
Calls are kept for the app setting `hook_events_keep_days` (Settings >
General, default now 30 days). The caller still only gets 202 Queued.
