Document ghost state continuity and tournament timeout

[themuffinator]

Motivation

• Clarify how the ghost reconnect system preserves player state beyond position to reduce confusion on rejoin.
• Make explicit that reconnects restore a player’s score, stats, and inventory when a ghost spawn succeeds.
• Call out tournament behavior so players and hosts understand that disconnects can trigger a short timeout window.
• Improve player-facing documentation consistency across the repo by updating both places the guidance appears.

Description

• Updated docs/wiki/players.md and wiki/Players.md to expand the ghost player system section and restructure it into How it works, Persistence rules, and Player tips.
• Changed the persistence wording to explicitly state that when a ghost spawn succeeds your score, stats, and inventory are restored, and preserved the existing note about g_ghost_min_play_time.
• Added a concise Tournament timeouts note under player tips to document the brief reconnect window used in tournament matches.
• Kept the existing safety-first respawn checks and fallback behavior documentation (blocked ghost spot logs and normal spawn fallback).

Testing

• No automated tests were run because this is a documentation-only change.
• Documentation builds or linters were not invoked as part of this change.
• Files changed: docs/wiki/players.md and wiki/Players.md were updated and inspected locally for the new text.
• No runtime or gameplay tests were executed because no code was modified.
