Fixes 4 bugs blocking AE1 acceptance scenario (rollup returns 0):

1. Decimal not recognized as numeric: PostgreSQL JSONB returns numbers
   as Decimal; _evaluate_rollup's isinstance(v, (int,float)) missed them.
   Added _to_float() helper (also excludes bool, an int subclass).
   Applied to _evaluate_lookup for JSON serialization safety.

2. add_relation_link clobbers record values: update_record_values does
   full-replace, so setting the relation field wiped amount/etc.
   Added merge_record_values (|| operator) and switched all relation
   link mutations to use it (add + remove + reverse cleanup).

3. enqueue_recalc ON CONFLICT DO NOTHING swallowed re-enqueues: once a
   task reached 'done', the unique constraint silently dropped new
   requests for the same (record_id, field_id) — field showed stale
   data forever. Changed to ON CONFLICT DO UPDATE: reset done/error
   tasks to pending; leave pending/calculating as-is (no double-process).

4. No cross-table recalc on record update: update_record_values only
   triggered recalc on the record's own table; rollup on the target
   table never updated when source values changed. Added
   _trigger_cross_table_recalc() — finds relation fields on the
   record's table, triggers recalc on linked target records.

Tests:
- AE1 acceptance: 3 e2e tests (SUM on insert, update-triggered recalc,
  AVG aggregation) — all pass against real PG.
- Bidirectional relation deletion: verifies _cleanup_reverse_link
  removes source from target's reverse field.
- SSRF guard: 3 tests blocking loopback, private IP, non-HTTP scheme.
- Updated test_recalc_deduplication for new ON CONFLICT DO UPDATE
  semantics (returns existing task, not None).
- Fixed test_crash_recovery to use stale_threshold=0 (was always broken
  with default 600s threshold).
