Fix pagination bug causing scenes to be skipped when count < per_page

[rustyinfinity]

Description

Fixed a pagination bug in processAll() where scenes were never processed when the total scene count was less than per_page (100)

Problem

The loop used integer floor division to calculate the number of pages:

for r in range(1, int(count / per_page) + 1):

When count < per_page (e.g. 4 scenes, per_page=100):

int(4 / 100) + 1 = 0 + 1 = 1
range(1, 1) is empty — the loop never executes
No scenes are fetched or processed

Fix

Use math.ceil instead of floor division so the loop always runs at least once when there are scenes to process:

for r in range(1, math.ceil(count / per_page) + 1):

So if scenes = 4 and per_page = 100

4/100 = 0.4 then math.ceil -> 1
