[FEATIRE REQUEST] Use the system certificate store in tvOS

[opacey]

Is your feature request related to a problem? Please describe. This is important
Immich Gallery does not check the System Certificate Store in tvOS when verifying HTTPS (TLS) connections to immich servers. I run Immich behind a reverse proxy which carries a certificate issued by my own Certificate Authority and I have installed that Root cert on tvOS, but Immich still says "the certificate is invalid". I do not wish to use LetsEncrypt as that is an external service. N.B, USer certs are installed on tvOS like this: Settings > General > Privacy > Share Apple TV Analytics (Highlight, dont click it) > Play/Pause > Add Profile

Describe the solution you'd like
I would like Immich Gallery to recognise the user certs installed in tvOS's certificate store - not just the well known public services like LetsEncrypt.

Describe alternatives you've considered
LetsEncrypt is an alternative signing service but it is external and beyond my control so I wish to use my own.

Additional context
None I can think of but will provide any further details requested.

Thanks for reading and for the great app - I really like it.
