improvement(planetscale): add placeholders to every input and fill missing docs intros

[waleedlatif1]

Summary

• PlanetScale block: every text input and selector now has a placeholder (service token ID and token had none, nor did most advanced fields); formatted fields show their shape (timestamps, ranges) and optional fields name their default
• Added the MANUAL-CONTENT intro section to the PlanetScale, Bitbucket, Modal, and Otter docs pages, the only generated integration pages missing one
• add-integration and validate-integration skills now require a placeholder on every text-entry and selector subBlock, and a docs intro section (with a template)

Type of Change

• Improvement

Testing

• bun run scripts/generate-docs.ts: no generated changes, and all four intros survive regeneration; docs:check passes
• bun run lint, block registry check, bun run check:audits, docs-manifest:check

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

Confidence Score: 4/5

[Low risk] Documentation and UI placeholder text updates.

The PR appears safe to merge, with two non-blocking copy corrections worth making.

Findings

1.  Major version hint omits exceptions ▶
2.  Modal token requirement overstated ▶

Summary

The PR adds PlanetScale input hints, hand-written introductions for four integration pages, and placeholder and intro requirements to the integration-authoring skills.

• The new hints and introductions largely match the existing integration contracts.
• Two pieces of copy need qualification: PlanetScale's major-version default and Modal's token requirement.

Major version hint omits exceptions The placeholder says the version defaults to the parent branch version. For a branch restored from a backup, PlanetScale ignores this setting; when there is no parent branch, it can instead use the database default branch's version. Someone configuring a restore could rely on a version choice that will not take effect.

Modal token requirement overstated This instruction tells readers to create and enter a proxy token to connect, but calling an unauthenticated Web Function requires neither token field. Readers who only want to call a public function are directed to set up credentials they do not need. Distinguish that case from endpoint operations that require a token.
