[PR] [core] Clean up field-level options when dropping columns [paimon]

["qingwei727 (via GitHub)" <gi...@apache.org>]

qingwei727 opened a new pull request, #7659:
URL: https://github.com/apache/paimon/pull/7659

   ### Purpose
     Fix IllegalArgumentException: Field xxx can not be found in table schema when dropping a column that has field-level options (e.g.
     fields.xxx.default-value).
   
     SchemaManager.generateTableSchema() removes the column from the field list but leaves its fields.<column>.* entries in options, causing
     SchemaValidation.validateFieldsPrefix() to fail. This fix removes those orphaned options during DropColumn processing.
   ### Tests
   SchemaManagerTest#testDropColumnCleansUpFieldOptions — creates a table with fields.extra_col.default-value, drops the column, and verifies both the
     column and its options are removed.
