docs(lxc102): OOM cronic pe 4GB -> 12GB + refresh tabel resurse cluster

Browse Source 
Alerta "OOM x2 on pvemini" (09:36) arata procese mici ucise (dbus-daemon,
oom_score_adj:200), dar mesajul kernel dadea containerul real:
oom_memcg=/lxc/102. OOM local containerului, nu presiune de host - pvemini
avea 24Gi disponibili si zram functional.

Baseline masurat cu ZERO sandbox-uri active: ~1.9GB (sbx 863M + claude 317M +
VS Code Remote 450M + docker/tailscale/portainer 205M). Un sandbox real mai
adauga ~1.9GB (containerd-shim) -> plafonul de 4GB era depasit sistematic.
Contoare cumulate: oom_kill 24, 9279 depasiri memory.high, memory.peak fix pe
limita, swap 510/512 epuizat.

Verificat explicit ca sbx NU are memory leak: RSS urca la ~863M la pornire si
se plafoneaza (esantionat la 10s timp de un minut).

Fix: pct set 102 --memory 12288 --swap 4096 (live, fara restart).

Tabelul de resurse din cluster/README.md era vechi (102 aparea ca "coolify
stopped", lipseau 110 si 171, RAM gresit peste tot) - regenerat din pvesh.
