It doesn't look like mold or yeast rafts, but rather it looks like a the beginning of a pellicle (a film with powdery white patches).
So, my standard pellicle talk...
The film is called a "pellicle". It indicates the presence of wild yeast and/or bacteria. The beer is safe to drink. We have no way to tell what microbes are present just by looking, or even by tasting. Many different yeasts and bacteria can survive in beer and form a pellicle. Lacto actually does not typically form a pellicle; that's a myth.
Mold is entirely different than yeast/bacteria. It appears fuzzy/hairy. Mold can produce toxins and allergens, making it unsafe. It's important to make a distinction.
You already kegged it and that's fine. Keep it cold and you almost definitely won't have any problems.
FYI it still has the wild microbes in it; they don't just live on the surface. The pellicle is just a byproduct of wild microbes exposed to oxygen at the surface.
Clean your equipment thoroughly after use. Soak in PBW or fragrance-free Oxiclean; disassemble and soak whatever moving parts you can.
Use a quality no-rinse sanitizer immediately before use.
Do not use a secondary vessel. It has zero benefit but rather it causes oxidation and increases risk of contamination.
Cheers
P.S. You called this a honey Kölsch. Did you by chance add honey to the fermenter? Honey contains wild microbes.
