fix: remove accidental SidebarPathFormatter changes from PR manaflow-ai#2148

PR manaflow-ai#2145 inadvertently included SidebarPathFormatter maxDisplaySegments
and shortenedPath truncation logic that belongs to PR manaflow-ai#2148
(sidebar path optimisation). This commit reverts ContentView.swift to
origin/main for SidebarPathFormatter while keeping only the mute-related
changes: TabItemView == guard, shouldMute/muteLabel vars, mute Button.
