perf: move cache lookups from NavHost route lambdas into screen composables

Route lambdas in NavHost run during navigation composition and should be
kept lightweight. Cache lookups (getNoteIfExists, checkGetOrCreateNote,
getOrCreateAddressableNote) and object construction (RoomId,
RelayUrlNormalizer) are now deferred to the screen composables themselves,
either via remember {} or inside LaunchedEffect blocks.

Affected screens: PublicChatChannelScreen, LiveActivityChannelScreen,
EphemeralChatScreen, GeoHashPostScreen, HashtagPostScreen,
ReplyCommentPostScreen, NewProductScreen, LongFormPostScreen,
ShortNotePostScreen, NewPublicMessageScreen,
ImportFollowListPickFollowsScreen.
