* fix: prevent RPC update handlers from accidentally clearing associations Proto3 repeated fields default to [] when not sent, making it impossible to distinguish "clear all" from "field not provided". This caused UpdateStatusReport, UpdateMaintenance, and UpdateNotification to silently delete all associations (page components / monitors) when only updating metadata like title or name. Add optional bool flags (update_page_component_ids, update_monitor_ids) to each update request. Associations are only processed when the flag is explicitly true. Deprecate the direct page_id field on UpdateMaintenanceRequest — pageId is now always derived from components. * ci: apply automated fixes * pr update --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
