feat: "hidden" input types for numbers and booleans

[cofl]

Adds input types "hidden number" and "hidden boolean" for numeric and boolean form fields. This allows numeric IDs -- post IDs, comment IDs, etc -- to be directly used in hidden fields without explicitly converting to/from strings, which better matches many common use cases.

Closes #14694

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

Edits

• Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.
