refactor(approvals): persist title+options on channel/sender approval tables

getAskQuestionRender used to hardcode the card title and option labels
for pending_channel_approvals and pending_sender_approvals in the
DB-access layer, duplicating wording that already lived in the approval
modules. That caused a visible drift between the initial card title —
picked per event in channel-approval.ts ("📣 Bot mentioned in new chat"
vs. "💬 New direct message") — and the post-click render, which
always showed the constant "📣 Channel registration".

Mirror the pattern already used by pending_approvals: add title /
options_json columns on both pending_*_approvals tables via migration
013, have the approval modules write them at creation time, and let
getAskQuestionRender just SELECT.

- Migration 013 ALTERs the two tables to add title + options_json.
- PendingChannelApproval / PendingSenderApproval types and their
  create functions grow the two fields.
- channel-approval.ts / sender-approval.ts normalize options once
  and pass both title and options_json into the insert.
- getAskQuestionRender drops the hardcoded render objects and reads
  the stored values.
