UI: amber accents, smaller wallpaper logo, new support bundle name, drop display resolution

- Bootloader: GRUB fallback text colors → yellow/brown (amber tone)
- CLI charts: all GPU metric series use single amber color (xterm-256 #214)
- Wallpaper: logo width scaled to 400 px dynamically, shadow scales with font size
- Support bundle: renamed to YYYY-MM-DD (BEE-SP vX.X) SRV_MODEL SRV_SN ToD.tar.gz
  using dmidecode for server model (spaces→underscores) and serial number
- Remove display resolution feature (UI card, API routes, handlers, tests)
