Add minimum peer upload speed setting and fix quality scoring tiers

New dropdown in Soulseek settings lets users filter out slow peers at
search time (Any/1/2/3/4/5/10 Mbps). Passes minimumPeerUploadSpeed
to slskd API in bytes/sec.

Also fixes quality scoring tiers which were using wrong units — old
thresholds (5000, 1000, 500) treated bytes/sec values as kbps,
making speed scoring effectively meaningless. Now uses correct
bytes/sec thresholds based on real peer data.
