fix(types,detail): derive five spec-named symbols instead of forking them (objectstack#4115)

Burns the first five names off the spec-symbol DEBT ledger (149 -> 144).
None of these were "one spec release away from drifting" — all five had
already drifted, and two were live defects:

- PageVariableSchema (zod/layout.zod.ts) omitted `source`, the entire
  ADR-0049 write-binding, so a spec-authored master/detail page parsed
  into a variable nothing could ever write; its `type` enum was also
  missing `record_id`, rejecting spec-valid record-picker variables. The
  sibling PageTypeSchema three lines below was already a spec re-export,
  with a comment describing this exact failure — one mirror was fixed and
  its neighbour left broken.
- FeedItemType carried 7 of the spec's 13 members. The six missing kinds
  (file, sharing, note, record_create, record_delete, approval) had no
  icon and no colour in RecordActivityTimeline, so a server emitting any
  of them produced an unrenderable feed item. Both maps are
  `Record<FeedItemType, …>`, so widening the union surfaced the gap as a
  compile error; the six entries are filled in here.
- PermissionAction was 8 of 11, missing `execute`/`manage`/`configure`.
- ObjectIndex lacked `fulltext`, `unique: 'global'` and `partial`.
- PageVariable (TS) was member-for-member identical to spec's — a second
  place to drift from and nothing else. Note its own Zod counterpart had
  drifted while it had not.

The ledger is regenerated with `--ledger`, not hand-edited; the diff is
exactly these five names, so no other package's debt was dropped.

Mutation-tested both directions: re-forking a burned-down name fails the
guard by name, and leaving a burned name in the ledger fails it as stale.
