The Hyprland IPC helper cached the socket folder with the first instance
signature already appended, so later calls ignored their instanceSig argument
and always reused the first path. That made the helper violate its own API even
though most real Waybar sessions only talk to a single Hyprland instance.
Cache only the base socket directory and append the requested signature per
lookup. This fixes correctness for tests, nested or debug multi-instance
setups, and future code that needs to resolve a different signature, without
claiming support for one Waybar process managing multiple Hyprland sessions.

The hyprland IPC fixture was no longer used by the current test setup.
I removed the dead fixture so the test code reflects the actual execution path
and is easier to maintain.

Hyprland tests did not explicitly verify descriptor behavior on key failure
paths.
I added focused tests for missing instance signature and connect-failure paths
that assert file descriptor counts stay stable across repeated attempts.

Allows us to disable modules entirely when socket connection isn't
working. This is similar to how sway handles their socket connections
disabling modules. This supports a single waybar config for multiple
IPCs.
