dayuan.jiang b0e95a5ef4 refactor(providers): one record per provider, ten name-keyed tables derived from it ...

Step 2 of the provider refactor plan. lib/providers.ts holds one record per
provider (SDK kind, credential kind, env prefix, default URL, picker group,
notes and base URL hints in four languages, and the short model list of the
six providers that cannot list models). ProviderName is now the record's
key set and lib/types/model-config.ts re-exports the record as PROVIDER_INFO,
so the twelve importers are unchanged.

Derived from the record, under their old names and in their old files:
FIXED_CRED_PROVIDERS, PROVIDER_LOGO_MAP and chatRequestUrl's own-path list
(model-config.ts), SINGLE_SYSTEM_PROVIDERS, PROVIDER_ENV_VARS and
SDK_KNOWS_ENDPOINT (ai-providers.ts), PROVIDER_GROUPS and OPTIONS_OPEN
(provider-setup.ts), NO_KEY_NEEDED (provider-models route).
tests/unit/providers.test.ts freezes the old tables' values and checks the
derived ones against them. The record is written in the picker's order, so
the provider lists in two 'No AI provider configured' messages change order;
those two snapshot rows are the only snapshot change.
