feat(sql): MySql provider over MySqlConnector, one shared provider map (lmxopcua#753)

Browse Source 
SqlProvider.MySql is now a constructed backend instead of a reserved name.

- MySqlDialect (Driver.Sql.Dialect): MySqlConnector 2.6.2 (MIT, fully managed,
  no vulnerable packages), backtick quoting with MySQL's 64-char / no-trailing-
  space rules, information_schema catalog SQL with the database as the schema
  (system databases excluded, aliases pinned), trailing LIMIT, a type map that
  also reads the reader-side spellings (INT UNSIGNED -> UInt32, BOOL -> Boolean).
- SqlDialects: the one provider -> dialect map. The factory, the Test Connect
  probe and the browse picker each carried their own switch (and drifted once);
  they now all read this, and their refusals list the supported/reserved sets
  from it.
- AdminUI driver form offers MySql.
- Tests: MySqlDialectTests (golden quoting/catalog/type map/planner SQL); the
  provider-gate tests in factory, probe, browser and form now treat MySql as
  supported and Odbc as the reserved control. MySqlReadTests + Docker/mysql
  (throwaway mysql:8.4, SELECT-only login): liveness, KV/wide-row/topByTimestamp,
  INT keys vs authored text, case folding against case-sensitive table names,
  catalog rejection, browse walk, factory+probe, named query with a bound
  parameter, and a writing stored function whose effect the rolled-back
  transaction discards.
