Add custom provider editor to API modes

Split provider management from API mode saving so users can add
and edit custom OpenAI-compatible providers in a dedicated
editor.

Require a full chat-completions endpoint URL for provider setup
and derive the paired completions endpoint with shared popup
utilities backed by unit tests.

Keep API mode provider binding explicit at save time and preserve
provider-secret synchronization in General settings for backward
compatibility.

Add provider-related locale keys across supported locales.
