Fixed: Corrected Site Health calculations and REST API responses so health scores accurately reflect each site's status, including sites with missing, malformed, negative, or critical issue data.

Fixed: Corrected multiple REST API v2 schemas and pagination settings for automatic updates, uptime monitoring, expected status codes, tag site counts, and client custom fields, including support for the deprecated pre_page alias.

Fixed: Improved REST API validation and response handling to reject malformed settings, prevent PHP 8 errors and unintended batch operations, validate custom option names, and exclude sensitive or internal data from responses.

Fixed: Improved REST API validation so invalid monitoring values, unsupported enum formats, and unsupported batch update requests return appropriate errors.

Fixed: Ensured uptime monitors correctly report a DOWN status when no HTTP status code is received.

Fixed: Resolved an issue that could leave the site removal process stuck in the "Removing" state on some hosting environments.

Updated: Redesigned the "Connection Status" widget with tabbed filtering, live connection totals, paginated site details, in-widget reconnection, and more accurate staging site status reporting.

Updated: Improved uptime monitoring retry scheduling so retries occur only after a valid retry time has been set and the configured retry interval has elapsed.

Updated: Improved REST API pagination compatibility and expanded schemas for monitoring settings, update flags, expected statuses, and site counts.

Updated: Replaced the generic __() JavaScript translation function with a namespaced MainWP translation helper to prevent conflicts with other scripts.

Dev: Added the mainwp_add_site_top_navigation and mainwp_add_site_tabs_content hooks to support custom navigation and tab content on the "Add Site" screen.
