refactor(students): migrate to Drizzle ORM and async queries
Replace raw sqlite queries with Drizzle ORM. Remove the connect helper and use the
shared db instance and schema definitions. Convert getItself, getAll and
addStudents to async functions, use eq and lt helpers, and simplify promotion
handling. This improves type safety, maintainability, and allows non‑blocking
database access.
Add type="button" to the EditMobility and UploadStudents buttons
to prevent default form submission behavior.
Include a key prop on Student components in Promotion for stable list rendering.
