Live testing against an AmneziaWG 2.0 server revealed the actual root cause
of "Failed to generate client keys": the official Amnezia container image
ships the userspace tool only as `wg` (a patched AmneziaWG binary) and has
NO `awg` binary, while the panel hardcoded `awg` for AWG2. `awg genkey` then
failed with "sh: awg: not found". (amneziawg-go ships `awg` with `wg`
symlinked, so both names work there — but the Amnezia image does not.)
- generateClientKeys(): detect the tool inside the container
(`command -v awg || command -v wg`) instead of hardcoding `awg`.
- addClientToServer(): resolve the tool via new resolveWgTool() helper so
`wg set` / `wg-quick up` (peer apply) also work on the Amnezia image.
- executeServerCommand(): delegate to VpnServer::executeCommand so SSH key
auth + docker sudo auto-detection apply to all 19 call sites (it was
password-only before).
Verified end-to-end on a live AWG2 server: pre-fix code fails with
"Failed to generate client keys: sh: awg: not found"; fixed code creates
the client, generates keys, and the peer appears in `wg show wg0`.

Issue #50 (AmneziaWG 2.0 / awg2): "Failed to generate client keys" when
creating clients, and "Invalid server response" on first install.
- VpnClient::generateClientKeys() built its own password-only SSH command
(PubkeyAuthentication=no, no sudo), bypassing VpnServer::executeCommand.
That broke key-based servers and hosts where docker requires sudo. Route
it through executeCommand so SSH-key auth and docker sudo auto-detection
apply, matching every other remote operation.
- VpnClient::getNextClientIP() read /opt/amnezia/awg/wg0.conf only; AWG2
uses awg0.conf. Read awg0.conf first, fall back to wg0.conf.
- deploy route: lift PHP time limit (set_time_limit(0) + ignore_user_abort)
so the multi-minute awg2 docker build is not killed mid-request, which
produced the truncated, non-JSON "Invalid server response".
- migration 070: drop `--no-cache` from the awg2 docker build so layers are
reused, making installs and retries fast and idempotent.
