Fix Landsraad System select height and width uniformity

Remove fixed height (38px) from Save Rules button and hardcoded width
(150px) from the select, allowing both to size naturally. The select now
uses flex: 0 1 180px (matching the pattern of bottom selects like Player/Task),
and both elements align uniformly without visual gaps.

Fixes #51.
