feat(plymouth): add custom-logo variant, sync answerfile + docs

- plymouth.sh: accepts PLYMOUTH_LOGO_SRC env var; PNG used as-is, SVG
  converted via rsvg-convert (librsvg only installed when needed)
- apps/plymouth-custom.sh: thin wrapper that validates the caller-supplied
  path and delegates to plymouth.sh with PLYMOUTH_LOGO_SRC exported
- install-modules.sh: adds 'Plymouth (custom)' checklist entry; prompts
  for image path via inputbox before the confirmation dialog; exports
  PLYMOUTH_LOGO_SRC into the module run
- generate-answerfile.sh: adds 'plymouth' (on by default) to the
  components checklist to match tui-install.sh
- docs: installation.md and modules.md updated with Plymouth component,
  answerfile schema, mkinitcpio note, and custom-logo module entry
