url.parse() deprecation warning persists due to mongoose@8.x pinning mongodb@6.x

Describe the Bug

The url.parse() deprecation warning (DEP0169) was partially fixed in Payload v3.69.0 (#14978), but still occurs because @payloadcms/db-mongodb pins mongoose@8.15.1, which depends on mongodb@~6.16.0.

The MongoDB driver 6.x uses url.parse() internally (e.g. in mongodb/lib/utils.js). This was fixed in mongodb@7.x, which ships with mongoose@9.x.

Dependency chain:

@payloadcms/db-mongodb → mongoose@8.15.1 → mongodb@~6.16.0 (uses url.parse)

Proposed fix: Upgrade to mongoose@^9.x which depends on mongodb@~7.1 (no more url.parse()).

Reproduction Steps

1. Create a Payload project with @payloadcms/db-mongodb
2. Run with NODE_OPTIONS=--trace-deprecation
3. Observe DEP0169 warning originating from mongodb/lib/utils.js (via mongoose 8.x)

Which area(s) are affected?

db: mongodb

Environment Info

Payload: 3.81.0 (latest)
mongoose: 8.15.1
mongodb: 6.16.0
Node: >= 21 (where DEP0169 is emitted)

Start with packages/db-mongodb/package.json at the dependency line mentioned in the issue, then verify the installed Mongoose and MongoDB versions. Reproduce with NODE_OPTIONS=--trace-deprecation and a Payload project using @payloadcms/db-mongodb. Done means the supported dependency upgrade is compatible and the DEP0169 warning no longer originates from mongodb/lib/utils.js.
