Remove crosshair network from (C)NEOPlayer datatable, simplify caching

[nullsystem]

Description

Crosshair is already now networked in player resource, so no longer needed to be networked from server to client in (C)NEOPlayer and turned into a simple array server-side. The networked crosshair caching also simplified in client-side crosshair HUD.

Found a bug where the crosshair gets stale.

I am moving fast this morning but I was able to cobble the repro together @nullsystem.

As for a fix, I think you just need to clear the cached compare string m_szLocalStrPlayerCrosshair[0] = '\0' whenever the non-spectator path imports into m_crosshairInfo. Like when inside the !bTakeSpecCrosshair block at hud_crosshair.cpp line 543, so the spectator path can never skip a re-import based on a cache that no longer describes m_crosshairInfo.

Bug reproduction steps

Two scripts

xhairtest.cfg

// Spectator crosshair repro, phase 1: launch.
//
// Tests a client-side caching issue where toggling cl_neo_crosshair_network
// off and back on while spectating a player can leave YOUR crosshair rendered
// instead of the spectated player's (relevant to the caching changes in
// https://github.com/NeotokyoRebuild/neo/pull/2053).
//
// Run from the console:  exec xhairtest
// After the map finishes loading, press F9 and follow the echoed steps.
//
// Prerequisite (one time): in Settings -> Crosshair, enable the HIPFIRE
// crosshair option for your own config. The stock default hides the
// crosshair entirely unless aiming down sights, so "crosshair visible at
// hipfire" is the signal that separates your crosshair from the spectated
// bot's default one.
//
// NOTE: this rebinds F8/F9/F10 (binds are archived in config.cfg).
// Restore your own binds afterwards if you use those keys.

// Keep the roster at exactly the one bot we add manually (quota default is 10!)
neo_bot_quota 0

// Deterministic starting state for the test
cl_neo_crosshair_network 1
crosshair 1

bind F9  "exec xhairtest_bots"
bind F8  "spec_next; spec_mode 4"
bind F10 "toggle cl_neo_crosshair_network 0 1"

echo ""
echo ">>> xhairtest: loading ntre_oilstain_ctg — press F9 once the map is up."
echo ""

map ntre_oilstain_ctg

xhairtest_bots.cfg

// Spectator crosshair repro, phase 2: bot + spectate.
// Executed by pressing F9 (bound in xhairtest.cfg). 
// Pressing F9 multiple times adds more bots.
//
// With players on only one team the round stays Idle, so no round transition
// fires the client-side crosshair cache resets (resetPlayersCrosshair) that
// could mask the stale-cache bug. If the bot never spawns while Idle, add a
// second bot on the other team (bot_add nsf noquota) to force a round start —
// the test still works, just run the toggles within a single round.

// nb_stop is cheat-flagged; cheats also let you freeze the bot later if wanted

echo ""
echo ">>> xhairtest steps:"
echo ">>>  1. Press F8 until you are FIRST-PERSON on XHAIRBOT (crosshair only draws in-eye)."
echo ">>>     While the bot is NOT aiming, seeing NO crosshair is correct:"
echo ">>>     its default config hides the crosshair at hipfire."
echo ">>>  2. Press F10 (network OFF) -> YOUR hipfire-enabled crosshair appears."
echo ">>>  3. Press F10 again (network ON), wait ~1s:"
echo ">>>       Expected: crosshair disappears again (bot default, hipfire hidden)."
echo ">>>       Bugged:   YOUR crosshair stays until the spec target changes."
echo ""

Launch options: +exec xhairtest
Crosshair settings: Make sure you have hipfire crosshair enabled for ease of testing.

Procedure

1. Launch. xhairtest.cfg auto-execs: binds F8/F9/F10, sets neo_bot_quota 0, loads ntre_oilstain_ctg.
2. Press F9 (runs xhairtest_bots.cfg: adds XHAIRBOT on Jinrai, puts you on spectator). If stuck on "NOT ENOUGH PLAYERS": bot_add nsf noquota, then optionally nb_stop 1.
3. Press F8 until first-person on any bot. Baseline should be no crosshair (bot default hides hipfire. crosshair only draws ADS/in-eye).
4. Press F10 (network OFF) → your crosshair appears.
5. Press F10 again (network ON), might be a frame delay on this one.

Correct: crosshair disappears. Verified on master
Bugged: your crosshair stays — and persists even when switching bots, since all bots share the identical default serial. Verified on nullsystem:XHairRefactorDataCache
