Add Schwab OAuth provider configuration & documentation

Registers the new schwab OAuth2 provider in packages/providers/providers.yaml, supplying authorization/token endpoints, proxy base URL, and documentation links. Adds Schwab-specific documentation (docs/api-integrations/schwab*.mdx), generated snippet content, navigation updates in docs/docs.json, and a new logo asset under packages/webapp/public/images/template-logos/schwab.svg to surface the integration in the docs and UI.

Key Changes

• Declared schwab provider metadata in packages/providers/providers.yaml, including OAuth endpoints, grant parameters, proxy base URL, and documentation pointers.
• Documented the Schwab integration via docs/api-integrations/schwab.mdx and setup guide docs/api-integrations/schwab/how-to-register-your-own-schwab-oauth-app.mdx with quickstart, setup steps, and usage guidance.
• Generated Schwab snippet artifacts (docs/snippets/generated/schwab/PreBuiltTooling.mdx, docs/snippets/generated/schwab/PreBuiltUseCases.mdx) and added the integration to docs/docs.json navigation.
• Added Schwab logo asset at packages/webapp/public/images/template-logos/schwab.svg for template branding.
