Add a second e2e suite that runs Traefik as a downloaded binary with the
plugin loaded from source, and replaces Crowdsec with a small stdlib-only Go
LAPI mock driven via /admin endpoints. No Docker, no real Crowdsec.
The mock lives in its own nested Go module (tests/e2e/mock/mocklapi) so it
stays out of the plugin module's build, lint, test and vendor.
This suite validates the plugin's own behaviour (live/none/stream modes,
caching, trusted-IP bypass, ban/captcha rendering). Crowdsec and AppSec
correctness are out of scope on purpose — they are validated upstream by the
maintainer — so the AppSec scenario is intentionally absent and the README
says so to avoid misfiled issues.
CI now runs this suite only (`make e2e_mock`), since it needs neither Docker
nor a real Crowdsec. The Docker suite (tests/e2e/scenarios) is kept for local
debugging (`make e2e`).
