Show pre-deleted table schemas and improve write errors

[Caideyipi]

Description

Tables and columns can remain in PRE_DELETE while a DROP operation is incomplete. Plain SHOW TABLES and DESC currently hide these objects, and attempts to write to or recreate them can report that they are missing or already exist.

• Include PRE_DELETE tables in SHOW TABLES without DETAILS, while continuing to hide PRE_CREATE tables. Keep pre-deleted columns in plain DESC and retain the existing presentation of pending type changes.
• Report that a table or column is being deleted, with guidance to wait or retry the DROP. Use SEMANTIC_ERROR so IF NOT EXISTS and automatic schema creation cannot suppress these failures as ordinary duplicates. Provide both English and Chinese messages.
• Check pre-deleted columns on the missing-column write path, once per request, including INSERT and TsFile loading with automatic schema creation disabled. Existing-column writes do not perform an additional RPC.
• Exclude pre-deleted columns from DataNode cache initialization, refresh, and column-extension schemas so these paths cannot restore their writability. DESC continues to use the complete metadata.

Validation

• 32 targeted unit tests passed across TablePreDeleteTest, TableHeaderSchemaValidatorTest, CreateTableProcedureTest, ConfigMTreeTest, and DataNodeTableCacheTest.
• Spotless and Checkstyle passed for the changed modules; English/Chinese message keys and placeholders match.
• Full-reactor English and Chinese test-compile -DskipTests passed for the affected reactor (Node Commons, DataNode, ConfigNode, and dependencies).

This PR has:

• been self-reviewed.
• added unit tests for the changed behavior and cache refresh/recovery paths.
