xAL6 dfb8c5d63c Encrypt.py: derive output filename from URL basename ...

The URL passed via --url (e.g. https://server/payload.dat) and the file
Encrypt.py wrote (data.enc) didn't match — operators had to rename the
file before uploading, which was both error-prone and pointlessly noisy
("data.enc" itself screams "encrypted blob" to any FS scanner).

Encrypt.py now defaults the output filename to the URL's last path
component, so encrypt-then-upload is a no-rename flow. --out <file>
overrides if a different name is needed.

  --url https://c2/payload.dat                 -> writes payload.dat
  --url https://c2/foo.bin                     -> writes foo.bin
  --url https://c2/x --out something.dat       -> writes something.dat

Downstream:
- tests/c2-integration/build-demos.py: reads ROOT/<label>.dat directly
  instead of ROOT/data.enc → ENC_DIR/<label>.dat.
- tests/c2-integration/run-loader-test.py: looks for payload.dat after
  the build step (URL basename is hardcoded to payload.dat for the runner).
- host-payload.py docstring + route handler: keeps /payload.dat as the
  primary URL; /data.enc still aliased for backward compat.
- SideloadGen.py deploy hint: updated.
- CLAUDE.md / README.md / web/static/index.html: docs updated to refer to
  the URL-basename convention instead of hardcoded "data.enc".
- .gitignore: payload.dat + *.enc added.
