theme: strip the remaining Persona punch from Hyprland and the popouts

Hyprland:
- Windows round at 8px, concentric with the porthole's 18px corners at
  the 10px gap, instead of square corners inside a rounded opening.
- Group tabs are solid hull slabs; the titles used to float over the
  wallpaper. The current tab is lifted a step with its title in the light.
- Motion rewritten to glide and settle: no overshoot curve, gentler
  popin, workspaces slide-fade a short way instead of sweeping the whole
  screen, and layers only fade so they never stack on quickshell's own
  slides.

Quickshell:
- Album art in the bar and the media popout is square in a hairline frame,
  not masked to a leaning chamfered shape; the accent slab under the
  popout art is gone, and a track change dips the title instead of
  tilting the art.
- The bar's equaliser is a five-hairline signal meter that rests as dots.
- Segment meters (system, battery, OSD) are 4px rows instead of 10-12px
  blocks; the toast fuse is a hairline; the clock's accent slab is a
  neutral divider.
- No hover pops: rail icons, tray icons, media transport buttons and
  P5Button no longer scale up or lunge sideways; the icon bump is reduced.

Terminal: ANSI bright black drops to #464d44. TUIs use it as a panel fill,
and at the outline grey it read as a flat light slab.
