Gitea writes one Action row per interested user-context. A push to an
org repo by user U produces two rows — one with user_id=U, one with
user_id=org — differing only in `id` and `user_id`. Polling both the
user feed and org feeds (which we do, and need to, since neither alone
catches every cross-namespace event) surfaced both rows; the
`gitea:{action_row_id}` id gave them distinct ids, so the upsert dedup
never fired and ~38% of events on org-repo project pages rendered
twice. Switch to a content-derived id keyed on (op_type, act_user_id,
repo_id, ref_name, comment_id, created) so the two rows collide on
upsert, and add a migration that re-keys existing rows to the same
formula while collapsing the duplicates already in the table.
