Security Deposits: California Ll: How to Distinguish Between Wear and Tear and Damage Pics Included

My question involves landlord-tenant law in the State of: California.

First time landlord. We bought a brand new home and rented it out to our tenants for 4 years. Everything was brand new. Their move-ins also stated the condition of everything as "New." Now the tenant is moving, and I performed a pre-move-out walkthrough and the home looks in poorer shape than I would have imagined. There are scuff marks all over the home, paint chips in multiple areas of the house, scratches and dent in the baseboard and door frames (to the point where you can see the wood). My question is, how do you determine what is wear and tear and damage? I listed the following as damage in the pre-walkthrough, however the tenant disagrees and says he will sue if I deduct anything.

1. Multiple chips of paint throughout home and scratches on baseboards and door frames (I know the scuff marks/repainting is all on me, but what about the chips and scratches on the baseboards? I would imagine those would be damage?)
2. Holes on outside of house from removal of satellite installation
3. Stove spark ignition doesn't work anymore (was never informed that it needed repair until I did the prewalkthrough inspection)
4. Garbage disposal has water damage (I read online average life span of a garbage disposal is 12 years, it's not broken in 4)
5. The tenants had two dogs, and there is a strong dog odor in the home

Here are some photos for your reference: https://imgur.com/a/omhVck8

Keep in mind, the home was brand new.

Would appreciate any advice and feedback.

Thanks
