[MS-1028] Fix pagination logic by adjusting pageSize calculation in RoomEnrolmentRecordLocalDataSource

[meladRaouf]

JIRA ticket
Will be released in: 2025.2.0

Root cause analysis (for bugfixes only)

First known affected version: not yet released

Current logic calculates pageSize = range.last - range.first, which skips the last item in the range when range.last == range.first + pageSize.
Update to:
pageSize = range.last - range.first + 1
to include the full range.

Testing guidance

Normal identification shows that the number of identified subjects in each range is off by one, typically one less than expected.
