Non-numeric pagination query params produce 500s across list endpoints

[3m1n3nc3]

Description

Multiple list endpoints parse pagination with parseInt(...) and guard with value < 1. Because parseInt("abc") is NaN and NaN < 1 is false, invalid values slip past validation and are passed to Prisma skip/take, which throws and returns a generic 500. There is also no upper bound on limit, allowing unbounded page sizes.

• Files: app/app/api/users/[id]/followers/route.ts, app/app/api/users/[id]/following/route.ts
• Parse with Number(...) || default, guard Number.isNaN, and clamp to [1, MAX].
• Add a test sending ?page=abc&limit=-5 and asserting a sane default response (not 500).
