coa.13: fix character-view crash on chars with >2 professions

SetItemButtonTexture now guards a nil IconTexture (was crashing whenever a button
didn't exist). UpdateViewIcons profession loop stops at the last existing _ProfN
button instead of indexing a nil frame; added _Prof3..8 so CoA chars (which can know
many professions) show more than 2. This was blocking the character detail view from
rendering when you clicked a char in the Account Summary.
