Fix record table not refreshing after merging records
The record table's virtualization state persists across navigations, so
when the table remounts after a merge redirect, none of the existing
reload conditions were satisfied and the table rendered stale data.
Add an isInitializedOnMount local state to
RecordTableVirtualizedInitialDataLoadEffect that guarantees a fresh
triggerInitialRecordTableDataLoad on every mount, acting as a fallback
when no other reload condition matches.
