_write_custom_endpoint builds a fresh entry dict from the request body and
assigns it over providers[endpoint_id], carrying nothing forward but api_key.
A providers.<name> block is not owned by that panel. It can carry keys the
dashboard has no field for, all of them load-bearing:
api_mode the protocol the endpoint speaks
key_env where the credential comes from
extra_headers per-provider HTTP headers (may carry credentials)
request_overrides extra body params
and a models map with more than the one model the panel names.
So an edit that only changes the default model destroys the rest:
BEFORE api_mode, base_url, extra_headers, key_env, model, models,
name, request_overrides
AFTER base_url, discover_models, model, models, name
FIELDS DESTROYED: ['api_mode', 'extra_headers', 'key_env',
'request_overrides']
The provider is left with no credential wiring (key_env gone, no api_key),
talking the wrong protocol, missing its proxy auth header — from a UI action
that said nothing about any of that. The models map also collapses to the one
named model, dropping the others and their context_length.
Merge onto the existing entry instead of replacing it, and merge the models
map rather than overwriting it. Managed fields still win, so the edit itself
still applies; a brand-new endpoint is unchanged. api_key keeps its previous
semantics — a supplied key overwrites, an omitted one leaves the stored key
in place (now via the merge rather than an explicit carry-forward branch).
