Remove incorrect pow -> power normalization

claude · claude · commit daaf4e698f58 · 2025-12-25T12:39:01.000Z
ClickHouse does not normalize pow/POW to power in EXPLAIN AST output.
It preserves the original function name case. Removing this incorrect
normalization enables 3 tests:
- 00756_power_alias
- 01681_arg_min_max_if_fix
- 03161_decimal_binary_math
