MainWP Dashboard 6.0.1

Fixed: Database update routines now check for and remove only schema elements that actually exist (columns and indexes), preventing errors during upgrades.
Added: Plugin search now includes a dedicated MainWP Child plugin card.
Updated: Improved update/install error handling to avoid noisy failures and reduce risk of incomplete updates.
Updated: Lower dimmer z-index, raise top header z-index to prevent UI elements overlapping.
Updated: Refine modal responsive rules to fix layering and sizing for the "Install Add-ons" modal.
Dev: A new public hook handler to "Log_Manager" that exposes log record retrieval via the
mainwp_module_logs_get_log_recordsfilter.
