Add schemaName support, docs, test, and release notes for Supabase replication custom schema

[Copilot]

• Understand PR Feature/supabase schemas #7963: adds schemaName option to Supabase replication plugin
• Apply code changes from PR Feature/supabase schemas #7963 to src/plugins/replication-supabase/index.ts and src/plugins/replication-supabase/types.ts
• Add migration for custom Postgres schema (private) for testing
• Add test for schemaName option in test/replication-supabase.test.ts
• Add documentation for schemaName in docs-src/docs/replication-supabase.md
• Add schemaName feature entry to docs-src/docs/releases/17.0.0.md
• Fix test breakage: only call client.schema() for non-public schemas to avoid Accept-Profile header causing "operation was canceled" errors in PostgREST

You are using the free Dexie.js based RxStorage implementation from RxDB https://rxdb.info/rx-storage-dexie.html?console=dexie
While this is a great option, we want to let you know that there are faster storage solutions available in our premium plugins.
For professional users and production environments, we highly recommend considering these premium options to enhance performance and reliability.

Error: The operation was canceled.

Fixed in commit 056dc69. The root cause was that calling client.schema('public') sends an explicit Accept-Profile: public HTTP header which some PostgREST setups reject, causing the "operation was canceled" error. The fix introduces a schemaClient variable that uses client.schema(schemaName) only when the schema is not 'public', and falls back to the plain client otherwise — preserving the original behavior for the default public schema.
