[13.x] Fix: add missing check for #[WithoutTimestamps] on model ignore touch - #61073

Adds the runtime cascade for `#[model(touches = [...])]`: after a
child model is created, saved, updated, deleted, or force-deleted,
every declared `BelongsTo` owner gets one
`UPDATE <owner> SET updated_at = ? WHERE <key> = ?` on the same
executor as the triggering write, so it joins an ambient
`DB::transaction` and rolls back with it.

- `EloquentModel` gains `TOUCHES`, `HAS_TIMESTAMPS`, `UPDATED_AT_COLUMN`
  consts; `RelationEntry` gains `related_updated_at_column`, collapsed
  from the target's two consts via the new `touch_column` const fn.
- `Model::touch_owners` / `touch_owners_with_tx` / `__touch_owners_via`
  are new trait-default methods, wired into all 10 write-path call
  sites (create/save/update/delete/force_delete + the five `_with_tx`
  shims) and into the soft-delete macro's inherent delete/force_delete
  overrides.
- `without_touching_on::<M, _, _>` adds a per-type suppression scope
  (Laravel's `withoutTouchingOn`), and the existing `without_touching`
  now also suppresses the owner cascade, not just direct `.touch()`.
- The macro validates `touches` at expansion time: every name must
  resolve to a declared `BelongsTo` relation, or it's a compile error.
- An owner with `timestamps = false` is skipped, not written and not
  an error (laravel/framework#61073); same for a NULL FK or a
  soft-deleted owner.
- Breaking change: `TOUCHES` moves from an inherent const to
  `EloquentModel`, since the cascade needs it reachable from a trait
  default. `Comment::TOUCHES` still resolves with `EloquentModel` in
  scope.

Deliberately out of scope: `restore()` does not touch (Suprnova's
restore is a raw UPDATE, not a `save()`), and the cascade is one level
deep and event-free (no parent hydration, no grandparent recursion, no
parent `saved` event) - both documented in manual/eloquent.md's "Why
Suprnova diverges".

Port refreshForUpdate with the shared refresh query path, upstream unit and integration coverage, and usage documentation. Preserve model key validation and relationship reload behavior.

Make relationship touching honor WithoutTimestamps and the same property/attribute precedence as model initialization. Disabled models could otherwise write updated_at, including on tables without that column. Strengthen the precedence cases and reconcile both attribute cache-order tests against the existing instance-based cache.

Complete the missing multi-attribute touch model test and documentation. Use the upstream keyed AsPivot lookup in the moved refresh helper; the rest of the trait lookup PR remains under reconciliation.

Validation: timestamp precedence regressions failed before the correction and pass afterward; SQLite relation touching verifies inherited disabling. Changed test files, affected Eloquent ParaTest, full source/type analysis, and scoped formatting pass. Refresh integration tests also pass after the final trait lookup correction.
