Proposed commit message

Change page_size and batch_size manifest variable type from text to integer - part 1

Several integrations declare page_size or batch_size manifest variables
with type: text when the value is always a positive integer. Fleet
performs no numeric validation on text fields, so a user can set these
to arbitrary strings. Changing to type: integer ensures Fleet rejects
non-numeric input.
