feat(catalog): accept any value as the First Of argument

[e54-bot]

Summary

Declare the First Of argument as Any in the catalog, so canonical validation accepts First Of(<any value>).

Per ADR-0014, pinned OverPy 9.7.10 emits First Of(<value>) (astToWorkshop.ts) for values the client rejects in a Boolean parameter. That deliberate emission rule is acceptance evidence for the wrapper's argument; the previous Array|EntityId was a presumption only.

Changes

• catalog.json: firstOf paramTypes[0] -> Any; catalog and pinned digest regenerated.
• Docs: source-attribution row citing the emission rule; First Of signature updated.
• Regression: Vector, Hero, Team Of, Map, Color, Button and Game Mode wrapped values validate and round-trip; arity is still checked.

Verification

cargo fmt --check, cargo clippy --workspace --all-targets -D warnings, cargo test --workspace --all-targets, workshop-catalog-gen check, git diff --check all pass.

The opy-rs half (removing the validation-first-of-wrapper gap after the version bump) remains a follow-up in that repository.

Refs #290 (partial: the opy-rs validation-first-of-wrapper gap removal remains, so #290 stays open).

[Teakowa]

Blocking: the PR body says Fixes #290, so merging it will auto-close #290, but #290 still has an unmet acceptance criterion: after the opy-rs bump, validation-first-of-wrapper must be removed. This PR explicitly says that work remains a follow-up. Remove the auto-close reference and leave #290 open until that acceptance criterion is satisfied. The implementation/tests/CI otherwise look correct.
