fix(handlers): deduplicate activity_logs rows by delegation_id in ListDelegations fallback

The activity_logs fallback path in GET /workspaces/:id/delegations returned
both the initial 'delegate' row (status=pending/in_progress) and the
terminal 'delegate_result' row (status=completed/failed) for the same
delegation_id. The agent's _refresh_queued_from_platform iterates these
rows and would scan the stale initial row first, never discovering the
terminal outcome.

Fix: Go-side deduplication in listDelegationsFromActivityLogs. Rows are
scanned in created_at DESC order; for each non-empty delegation_id the
first occurrence is kept and subsequent older duplicates are skipped.
Rows with an empty delegation_id (pre-#318 records) are returned as-is
since they cannot be correlated.

Also fixes delegation_list_test.go activity_type values to match actual
handler inserts: all delegation activity_logs rows carry activity_type
'delegation' (not 'delegate' / 'delegate_result').

New tests:
- TestListDelegationsFromActivityLogs_DeduplicationKeepsNewest: verifies
  that when both rows exist for a delegation, only the newest is returned
- TestListDelegationsFromActivityLogs_DeduplicationDistinctDelegations:
  verifies distinct delegation_ids are all returned
- TestListDelegationsFromActivityLogs_DeduplicationMixedTerminalStatuses:
  verifies completed and failed terminal rows are correctly kept over
  initial pending/dispatched rows

Closes: backlog item #11 (Delegations list endpoint mismatch)
