Description

binary_copy_to_table now passes column names through quote_ident when building the COPY table(col1, col2, ...) clause, so identifiers that need quoting (e.g. a-b) work without callers wrapping names in double quotes manually.

Motivation and Context

copy_records_to_table already quoted column names; binary_copy_to_table joined raw strings and caused syntax errors for non-simple identifiers.

Closes #71

How has this been tested?

• Added python/tests/test_binary_copy_quoted_columns.py (table with "a-b", binary COPY with columns=["a-b"]).
• prek run -a
• cargo fmt --check and cargo clippy -p psqlpy --all-features with the CI warning flags
• pytest -vv --ignore=python/tests/test_ssl_mode.py: 262 passed against local PostgreSQL 16. test_ssl_mode.py was not run locally (no SSL-enabled Postgres here); CI covers it.
