Feature/publish abc clinical demand forecast 4.0.0 (#5671)

- Added abc-clinical-demand-forecast-4.0.0.json schema file
- Updated catalog.json to include version 4.0.0 and set as default
- Updated schema-validation.jsonc with validation configuration
- Added positive test case for version 4.0.0
- Copied negative test cases from version 3.0.0

Key changes in version 4.0.0:
- Added optional enrollmentStartOffset property in two object definitions
  (one for child-region defaults, one for actual-value-with-inherit).
  Type: integer or null. Minimum: 0. Default: 0. Represents months from
  site activation until first enrollment (First Patient In lead time).
  Null means inherit from parent; the default-for-child-regions variant
  defaults to 0 if no ancestor sets a value.
- The property is NOT in any required array, so existing 3.0.0 data
  validates against 4.0.0 unchanged. The major-version designation
  reflects that the new property meaningfully changes lead-time behavior
  for downstream consumers even though the schema permits omitting it.

Testing:
- Validated schema-specific: node ./cli.js check --schema-name=abc-clinical-demand-forecast-4.0.0.json (PASS)
- Validated full test suite: node ./cli.js check (PASS, all 806 tested schemas)
- Re-ran node ./cli.js check after rebasing onto current origin/master and
  after folding in pre-commit.ci auto-fix formatting: PASS, no errors or
  failures.

Rebase note: this branch was rebased onto origin/master to resolve merge
conflicts. The original 2.0.0 and 3.0.0 commits on this branch were dropped
because those versions were already merged upstream via PR #5670. The
pre-commit.ci auto-fix commit's formatting changes for the 4.0.0 schema
(compact enum arrays, AUTO-GENERATED header comment) were folded into this
commit so the rebased branch matches what the bot would otherwise re-push.
