Use prefixed table name, add case-insensitivity

[tpellissier-msft]

Round 2 of #39

This time, interpret tablename as the SchemaName in create_table and persist that in the table directly.

More details to be added once we discuss and decide if it's what we want.

Pull Request Overview

This PR implements case-insensitive table and column name handling in the Dataverse client, with a significant change to how table names are interpreted: table_schema_name parameters now represent the SchemaName directly rather than being normalized with prefixes. The changes add helper methods for case normalization, update parameter names throughout the codebase from logical_name to table_schema_name, and modify metadata lookup to use LogicalName (lowercase) for case-insensitive queries.

Key changes:

• Added case-insensitive cache key normalization and automatic lowercasing of column names in CRUD operations
• Changed table creation to accept SchemaName directly as table_schema_name parameter
• Updated all public APIs to use table_schema_name parameter instead of logical_name
