Enable Conversion from SQL Files to @Sql Annotations on DAO Methods

[xterao]

This update extends the existing conversion functionality so that the action can also be executed directly from the DAO method side.

• The action "Convert to @SQL annotation (set sqlFile=false)", which was previously available only on SQL files, is now also accessible on DAO methods.

• The action will remain available on the SQL file side as well, ensuring users can choose whichever entry point suits their workflow.

Conversion to a Sql annotation:

• The SQL file must exist.
• A Sql annotation must not already exist.

Conversion to an SQL file:

• A Sql annotation must exist.

Note: When a Sql annotation is present, the corresponding SQL file is not referenced, so duplicate registration of Sql annotations is not expected.
