increase app pagination to 100 and support multiple pages

[kc9wwh]

Description

Resolves an issue where OIDC clients beyond the default page limit were excluded from the dashboard.

Pocket ID's GET /api/oidc/clients endpoint paginates results by default with a limit of 20 items per page (pagination[limit]=20). Previously, PocketIDService.fetchApps() made an unparameterized request, causing any applications on subsequent pages (client #21+) to be silently dropped.

This change updates fetchApps() to:

• Request 100 items per page (pagination[limit]=100) to minimize round-trip requests.
• Loop through all result pages using pagination[page] and pagination.totalPages until every client is retrieved.
• Add structured debug/info logging with app counts and names for easier troubleshooting.

Fixes #21

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Manual test: Verified that all configured applications across multiple pages (including newly added OIDC clients) are fetched and rendered properly in the dashboard. Inspected server logs to confirm multi-page retrieval and total app counts.
• Automated test: npm run check
