[TF2] Add tf_player_team_debug command

[Kacey2k]

Description

Adds the client console command tf_player_team_debug, which prints identifiers and current team assignments for connected players.

The output includes:

• Session user ID
• Steam3 ID, or BOT
• Native team ID
• Human-readable team name

Example Output:

# userid uniqueid           team_id team
#      2 [U:1:1511176553]         2 RED
#      3 BOT                      3 BLU

The command reads replicated C_TF_PlayerResource data and does not depend on a Game Coordinator lobby. It produces no output when no player resource is available.

Team values follow TF2's existing definitions:

• 0 = Unassigned
• 1 = Spectator
• 2 = RED
• 3 = BLU

This provides a small diagnostic command for inspecting player team assignments, which benefits countless community projects that rely on console inference to function.
