feat(hyprland): float+center Bluetooth + printer config dialogs

Conservative first cut of the floating-window audit (item 41): float and
center the two shipped, unambiguous config dialogs — blueman
(manager/adapters) and system-config-printer — alongside the mixer. Uses
(?i) class regexes tolerant of the XWayland `.…-wrapped` form, consistent
with the existing (?i) usage in this file.

Deliberately conservative: network is dmenu/nmtui (no GUI editor), and the
polkit prompt + GTK file portals are deferred because their window class
can't be verified headlessly — a guessed class is a dead rule. Those wait
for a hardware `hyprctl clients` read (queued).

+  Broaden the windowrule float set beyond the mixer.

+  blind list). Network is dmenu/nmtui (no GUI editor → no rule). Confident,
+  shipped, unambiguous dialogs: **blueman** (manager + adapters) and
+  **system-config-printer**. Deferred polkit (hyprpolkitagent exposes no

+  two, `(?i)` regex tolerating the XWayland `.…-wrapped` form. RE2 `(?i)`
+  is already relied on in this file (line ~47), so it's consistent.
+- **Verified:** V0 green; `nix eval` confirms the rendered regex escaping
+  is correct (single backslash, `?` quantifier unescaped). Whether the
+  classes actually match live is V3 (queued — includes confirming the
+  regex catches the real class).
