CLAUDE: Add cuas_reuse_non_centered and cuas_reuse_centered config parameters

Replaces hardcoded `boolean reuse_non_centered = true` with a config parameter.
Adds a companion `cuas_reuse_centered` parameter: when true, attempts to load
ROUND_TWO_GOOD before starting computation and returns early if found, bypassing
both phases. Both default to true — missing files behave as if set to false.
Wired into dialog, properties (.corr-xml), and copy() in IntersceneMatchParameters.
