feat(byok): show qodercli custom providers in the model selector (#67)

SDK-spawned sessions run qodercli in its "sdk" runtime mode, which keeps CLI-configured custom providers (self-defined base URLs) disabled unless QODER_SDK_CUSTOM_BASE_URL_BYOK=1 is present — so their models never reached Qoderian. Opt every spawned CLI into that setting at the shared spawn boundary and group models with source "custom" under Custom, next to the existing BYOK ("user") ones. The catalog stays a plain live fetch: asking the server for providers by id rejects it with a 400.
