Add real server pool, race roster overhaul, and ship energy system

Server browsing & matchmaking:
- HL2-style main menu (QUICK PLAY/SERVER SELECT/OPTIONS/PROFILE/QUIT)
  replaces the old CASUAL/RANKED tiles; RANKED removed end-to-end
  (menu, matchmaking-api's Mode.ranked queue path, MMR matching) until
  ranked is real.
- New menu/server_select.gd lists real servers from the matchmaking
  API's GET /servers and connects directly, retiring the old
  unreachable menu/server_browser.gd.
- Real game-server pool: NetworkManager.host_server() self-registers on
  boot and heartbeats every 8s with live player counts; API computes
  available/full status from player_count, and a background sweep marks
  any server offline once its heartbeat goes stale (catches a crashed
  server that never deregistered).
- Server-select rows get a live UDP ping probe (query port = game port
  + 10000) instead of trusting stale DB numbers; post-connect HUD shows
  live RTT off ENet's own peer stats.

Race roster overhaul:
- Swapped Terran/Mechanos/Vorg for the pivoted roster — Apex Dynamics,
  Inner Sphere Navy, Outer Rim Collective — each with a 3-ship
  Fighter/Gunner/Tank lineup, art cropped from concept sheets with
  background removal + orientation fixes per sheet.
- Live headcount + roster + "TEAM FULL" lock on the race-select screen,
  shared between the initial pre-spawn pick and the pause menu's live
  SELECT TEAM swap.
- Bot personalities (bots/bot_personality.gd): aggression/caution/
  accuracy/reaction/awareness traits rolled per bot instead of one
  fixed AI profile.

HUD additions:
- Player list (roster, teammates white/enemies yellow, bots flagged),
  kill feed, minimap, and explosion VFX on death.
- Health and energy now render as bars (hud/stat_bar.gd) instead of
  text in the top-left HUD.

Ship energy system:
- Per-role max energy (Fighter 100 / Gunner 150 / Tank 250), 75 energy
  per shot, flat regen (100 per 2.5s), fully server-authoritative and
  piggybacked on the existing per-tick state broadcast alongside health.
- New blue "mirrored" bar top-middle of the screen (hud/energy_bar.gd)
  whose fill drains from both edges toward the center instead of
  left-to-right.

Ship handling tuning:
- Turn rate reduced (4.0 -> 1.0 rad/s) so a quick tap no longer
  over-rotates; holding past 0.15s ramps to double speed (2.0 rad/s) for
  fast full turns, gated the same way damage already is so replay during
  reconciliation can't double-count the hold timer.

 # Task Log
 
+Task 1
+
+I want to build an energy system for each ship.  Below the health put an energy of 100/100 for the fighter/ 150/150 for middle ship and big ship 250 energy.  Each bullet takes 75 to shoot.  Have a blue energy bar that is mirrord top middle appear at the top .  Have it take 2.5 seconds to refill 100
