Databricks: enable query and nested type syntax

[EthanVieira]

Enable existing parser capabilities for the Databricks dialect:

• MAP<key, value> nested types
• Backslash-escaped string literals
• SELECT * REPLACE
• FROM-first queries
• Pipe syntax (|>)

The pipeline negative test now uses CALL 123 invalid because Databricks permits numeric-leading identifiers, making the previous 123invalid input valid. The replacement remains invalid for every dialect covered by the test.
