android: your own Soulseek interests, and who the server says is like you

Community's fourth tab is Taste: the likes and hates this client
publishes to the Soulseek server (slsk_interests_mine, slsk_interest_set),
added and taken back as chips, and the people the server ranks as close to
them (slsk_similar_users) — a row each into the peer sheet the app already
has. Every declaration asks the server again and the chips stay quiet
until it has answered, the way the desktop does, because the ranking only
moves when its input does. The lists live in taste.svelte.js, read once
per account when the tab is opened; the mock walk declares a like, watches
the match grow, declares a hate and takes the like back.
