Improve cl_show_ids: support spectator menu, optimize, refactor

Also show client IDs in the spectator menu when `cl_show_ids` is enabled. Previously, this setting applied to scoreboard and chat, although the setting and config variable descriptions were only mentioning the scoreboard.

Extract client ID formatting in `CGameClient::FormatClientId` function to reduce duplicate code and ensure it is consistent.

Correctly indent client IDs also when largest client ID is 100 or larger. Fix scoreboard spectator client ID buffer not being large enough for IDs 100 and larger.

Make client ID formatting more efficient by avoiding `str_format` except for formatting the number itself and appending text directly to the text cursor when possible.
