⚙️ feat: Add ?type= query filter to GET /lab-notes

[AdaInTheLab]

Summary

Adds optional ?type= query parameter to GET /lab-notes, enabling clients to filter published notes by type (e.g. GET /lab-notes?type=tail).

Changes

• Import ALLOWED_NOTE_TYPES into the lab notes route handler
• Read and validate req.query.type against the canonical allowed set
• Inject conditional AND type = ? clause into both locale-filtered and unfiltered SQL queries
• Invalid or missing type values silently return all types (no breaking change)

Usage

GET /lab-notes?type=tail          → only tail-type notes
GET /lab-notes?type=lore          → only lore-type notes
GET /lab-notes?type=tail&locale=ko → tail notes in Korean
GET /lab-notes?type=invalid       → all notes (graceful fallback)
GET /lab-notes                    → all notes (unchanged behavior)

Testing

• npx tsc --noEmit — clean
• npm test — 41/41 passing
• Pre-commit hook passes
