style(debug): reformat .cfbg debug into grouped, aligned sections

[Nyeriah]

Follow-up to #157 — pure reformat of the .cfbg debug output, no behaviour change.

Summary

• Splits the dump into Header / Faction / State / Fake record / Wintergrasp sections with consistent label widths and one value per line.
• Renders WG set membership as a two-column Alliance / Horde table instead of the inline Queue A/H=Y/- Invited A/H=... string.
• Adds an oddities count next to the section title (Oddities (3):).

Example output

=== CFBG debug: <Name> ===
  GUID: ...
  Config:  System=yes  WG=yes

  Faction
    Native     Alliance  (race 1)
    Current    Horde     (race 5)
    BG team    Horde
    Display    20578 (current) / 19724 (native)

  State
    Faked              yes
    Playing native     no
    In battleground    no
    Class / Gender     2 / 0
    Preferred race     0
    Forget BG players  no
    Forget in list     no

  Fake record
    Fake  team=Horde     race=5  morph=20578
    Real  team=Alliance  race=1  morph=...  nativeMorph=...

  Wintergrasp
    In WG zone   yes (zone 4197)
    War time     yes
    Player in sets:
                   Alliance  Horde
      Queue           -        -
      Invited         -        -
      In war          -        Y

  Oddities (1):
    ! Current team (Horde) does not match core WG side (Alliance)

Test plan

• .cfbg debug on a player outside any BG/BF — visual check, no oddities.
• .cfbg debug on a faked player in WG during war — visual check, oddities and set table populated as expected.
