perf(bitbucket): increase server page limit to 1000 for fetching all repos

Requests 1000 repos per page instead of defaulting to 25, reducing the
number of API calls needed to enumerate large Bitbucket Server instances.
The server silently caps at its configured maximum (page.max.repositories),
so pagination via isLastPage/nextPageStart remains correct regardless.
