feat(sql): Odbc provider — ANSI SQL:2008 profile over System.Data.Odbc (lmxopcua#753)

SqlProvider.Odbc is now constructed; every enum member is a working backend.

- OdbcDialect: System.Data.Odbc 10.0.14 (no vulnerable packages), ANSI double-
  quote quoting, positional `?` markers, INFORMATION_SCHEMA catalog (system
  schemas of the common backends excluded by name — the live gate caught
  psqlODBC listing pg_catalog), FETCH FIRST n ROWS ONLY limits, a conservative
  1000-parameter chunk. Positional binding is safe because every caller adds
  parameters in marker order (planner IN list, catalog schema-then-table).
- Named queries on a positional provider are checked by `?` count against the
  declared params (literals/comments ignored), since there is no name to match.
- Supported backends are those whose SQL accepts that profile (PostgreSQL via
  psqlODBC proven, Snowflake-like); SQL Server/MySQL/DB2 should use their native
  provider. The host needs the ODBC driver manager + vendor driver.
- Reserved-provider controls in factory/probe/browser tests now use an
  undeclared ordinal (99); the AdminUI form offers Odbc and a test pins the
  dropdown theory to SqlDialects.Supported.
- Tests: OdbcDialectTests (unit, any host). OdbcReadTests + Docker/odbc/
  run-odbc-gate.sh run the built suite in a throwaway Linux SDK container with
  unixODBC + psqlODBC against a throwaway seeded PostgreSQL: KV IN-list
  positional binding, where-pair, topByTimestamp via FETCH FIRST, a two-
  parameter named query, and the browse walk. macOS has no vendor ODBC driver,
  so there the suite skips.
