tools in all containers + apt GPG fix for 2026 clock + target dropdown fixed

- all 6 Dockerfiles: vim curl wget netcat git python3-pip now installed
- apt-insecure.conf (AllowInsecureRepositories) copied into images so
  participants can apt-get install despite expired Ubuntu/Debian GPG keys
- warmup base ubuntu:20.04 (EOL, GPG expired) -> ubuntu:24.04
- installed vim+git live into all 18 running team containers
- team portal target dropdown reloads after login (was empty pre-auth)
- attack log endpoint + A/D submit (attacker vs target) verified e2e
