What changed

Slice (b) of CL-11917, stacked on #54. Existing Settings screens and controls are unchanged.

• The add-provider dialog has a Custom endpoint tile: name, API type (OpenAI Chat Completions, OpenAI Responses or Anthropic Messages), base URL, key or the Keyless switch with its tooltip, and models (Model ID, optional Name, Context window, Output cap, each labelled).
• Custom providers sit in the existing Providers list with quiet Edit (same form) and Remove (react-ui ConfirmButton). A bordered-button version is in the screenshots for comparison.
• Saving tests the connection first. A keyless endpoint is tested with no key header at all; that part is in feat(hub): let people add custom model providers and models #54.
• Profiles list a custom model by its Name (or its ID when unnamed) under its provider. A custom provider counts as connected once saved, because custom connections are never probed on read; a disabled one shows as unavailable.
• needsBaseUrl was false on every shipped entry and is removed from the hub, the schema and the web.
• All wording is in apps/web/src/config.ts. One small layout rule uses existing tokens.

How it was verified

• Checked by hand on a throwaway stack with a fake endpoint and fake keys: add with a key, add keyless, edit, remove, and save a profile on a custom model and make it active.
• bun run test (79 pass), the e2e suite, lint, format and typecheck pass.
• Before and after screenshots are in a comment below.

The local Tip in apps/web/src/pages/custom-providers.tsx is a stopgap: @corbits/react-ui only offers InfoTooltip on its glyph. CL-11941 adds a general Tooltip to react-ui; once it's released, a follow-up bumps the pin and deletes Tip.
