…intainer review (OtterMind#1914) - strengthen OracleIdentifierProcessor: INSTANCE, escapeString with single-quote doubling, static escapeIdentifier/quoteIdentifierAlways - OracleMetaData processor singleton delegates to INSTANCE; private escapeSqlLiteral (OtterMind#2052) unified to processor escapeString - builders/DBManager/enums/value processors use the processor (or OracleSqlGuards for non-escapable validation) - OracleSqlEscapes removed; tests migrated (33 green)

Part of the SQL-injection hardening tracked in #1914. Prior art: #2052 (Oracle), #2053 (SQL Server), and the wave-1 batch (#2172-#2177).
These are second-order injection paths: values such as table/schema/view/index names originate from the connected database's own metadata, so exploitation requires a maliciously named object in a target database.
What changed (53 sites)
Completes PR #2052: extends escaping to all remaining metadata/DDL sites (DBMS_METADATA calls, data-dictionary SQL, DBManager, builders, type enums, RAW/BLOB value processors). Whitelists for sort direction/units/defaults accept legitimate quoted defaults.
