refactor(hfserver): read details with the shared keyvalue parser (#5232)

fn_info_game_hf now reads the Holdfast config with the shared fn_info_game_keyvalue_pairs_space parser (fixed in #5231) instead of its own sed lines. details no longer shows a trailing carriage return from the CRLF stock config.

Related to #4051
