v0.23.0

• Added a "Hide locked tags" checkbox to the "All tags" table (below the Quick sort links), checked by default, so locked tags stay out of the way while working the list. Persisted per-user like the usage-bucket filter (WPTO_Admin_Page::get_hide_locked_tags()); filters via a meta_query on wpto_locked in both wp_count_terms() and get_terms() in WPTO_Tag_Stats_Table::prepare_items().
• Fixed the "All tags" table losing an active search (and sort/bucket filter) when paging past page 1. The #wpto-tags-filter form posted via method="post", so s/orderby/etc. never made it into the URL that WP_List_Table's pagination links are built from; switched the form to method="get" and updated the bulk-action handlers (maybe_process_stats_tab_actions(), process_bulk_delete(), process_bulk_toggle_lock(), the add_to_merge branch in render_stats_tab()) to read tag_id[]/action/action2 from $_REQUEST instead of $_POST to match.
• Converted single-row lock toggle, single-row delete, and the "Lock"/"Unlock"/"Delete" bulk actions on the "All tags" table to Ajax (new wp_ajax_wpto_toggle_lock, wp_ajax_wpto_bulk_lock, wp_ajax_wpto_delete_tags handlers), so those no longer reload the page and drop the current search/sort/pagination state. Rows update or fade out in place; the "Hide locked tags" checkbox is respected when a row gets locked via Ajax. The full-page-reload routes (process_toggle_lock(), process_bulk_delete(), process_bulk_toggle_lock()) are kept as a no-JS fallback. The "Add to merge selection" bulk action is intentionally left as a normal (non-Ajax) submit, since it needs to redraw the merge basket section below the table anyway.
