Description

• It fixes !45901
• Backport of Feat: rename oversized containers from their edit form #1248 to GLPI 11.
• When a container's computed table name exceeds MySQL's 64-character limit, the plugin now disables it instead of crashing, and shows a rename form directly on the container's edit page.
• Submitting a shorter name renames the container and reactivates it; if a table with matching data already exists under that name (e.g. after a version migration), its data is preserved instead of being replaced by an empty table.
• plugins:fields:check_database now also reports container/item type pairs with no matching table, and tables with no matching container/item type pair.
