fix: name+guard Woodcutting/Woodworking, drop regex+deprecated this+InterfaceOptions guards

ProfessionMenu.lua:
- profList: add Name="Woodcutting" (spell 13977860) and Name="Woodworking"
  (spells 1005008-1005011) so getProfessionRanks can find the matching
  GetSkillLineInfo entry. Without Name, both fell through GetSpellInfo+match
  with no result and returned nil,nil.
- getProfessionRanks: replace compName:match(name) (regex) with compName == name
  (plain compare); GetSkillLineInfo names are exact, regex was a bug magnet.
- Guard rank concat at lines ~394/397/400: skip the " (rank)" / " (max)" /
  " (rank/max)" append when getProfessionRanks returns nil so unknown
  skill lines don't error.
- InterfaceOptionsFrame:HookScript: wrap in 'if InterfaceOptionsFrame then';
  CoA's reworked FrameXML has no InterfaceOptionsFrame.

ProfessionMenuOptions.lua:
- Guard InterfaceOptionsFrame / InterfaceOptionsFrame_OpenToCategory /
  InterfaceOptions_AddCategory call sites (Options_Toggle, ProfessionMenu_
  OpenOptions, CreateOptionsUI). All nil on CoA's FrameXML.
- TxtSize dropdown func: drop deprecated WoW-2.x global 'this'; use
  UIDropDownMenu_GetSelectedID(ProfessionMenuOptions_TxtSizeMenu) instead.
