Etcher is privacy-invasive; replace it in INSTALL.md, the USB upgrade
tool messages, and the live-boot ephemeral warning.

- New INSTALL.md consolidates all install paths: WROLPi Portable (Live
USB) as the headline option, plus Debian 12, Raspberry Pi, and Docker.
- README install sections collapsed into a single Install section that
links to INSTALL.md.
- UPGRADE.md gains an "Upgrading a WROLPi Portable USB" section covering
scripts/wrolpi-usb.sh upgrade, and documents that in-place conversion
of an existing data drive is not supported (backup -> flash -> restore).
- wrolpi-usb.sh install now prints that supported procedure instead of a
"not implemented" stub; debian-live-config/README.md documents the same.
