USelectEntity: fixed "More" button in dropdown closing the list instead of loading additional items. Root cause: click-outside handler captured a stale undefined ref for the options container (due to v-if), and showMore() called toggleDropdown() which toggled the dropdown closed
clickOutsideDropdown mixin: resolve $refs.options dynamically on each click check instead of capturing it once at mount time
addClickOutsideListener: accept a getter function (in addition to array) for dynamic ref resolution
UTableEntity: fixed multiple success notifications on multi-delete when several tabs
with the same entity are open. Moved alert from entity:changed event handler (fired in
every subscribed tab) into the store action (fired only in the initiator)
UTable: prevent calling column.formatTooltip for table header tooltips to avoid unnecessary JSON.parse exceptions on plain-text column labels (e.g. "Document Image")
el-notification: enable word breaking for notification content
u-auto-field: fixed issue where label-position="right" prop was propagated to UCheckbox, triggering unnecessary validation error. Removed validation that didn't affect functionality
