Fix: remove broken applyFilterText in DibiFluentMssqlDataSource causing NN-prefix with Dibi 4.1+

The MSSQL-specific override used direct string interpolation for LIKE searches
(SQL injection risk, wrong double-quote string delimiters for MSSQL) and called
escapeText() in a way that resulted in double N-prefix (NN'...') with Dibi 4.1+
SqlsrvDriver. Removing the override lets the base class implementation handle
text filtering correctly via the %%~like~` modifier which invokes the driver's
escape method exactly once.

Fixes #908
