Subject: [PATCH] fix(jira): use paginated project endpoint in
 get_organization_config

The settings page called get_projects_list() which hits the deprecated
unpaginated GET /rest/api/2/project endpoint, returning every Jira
project in a single response. For large enterprise instances this
causes timeouts, leaving the configuration page with an infinite
spinner.

Switch to get_projects_paginated(maxResults=50) so the initial
settings-page render is bounded. Projects beyond the first 50 are
accessible via the existing typeahead search endpoint (JiraSearchEndpoint),
which already uses the paginated API.

Fixes #95257
