fix(ledger-browser): supabase advisor errors and warnings

[outSH]

Describe the bug

Supabase reports multiple errors and warnings in it's advisor which should be resolved.

To Reproduce

• Follow the setup guide using Supabase Cloud (not sure if advisor is available on local deployment).
• Install Ethereum and Fabric browser apps using test data setup (e.g. https://hyperledger.github.io/cacti/cactus/ledger-browser/plugin-apps/ethereum-browser/#test-data-setup)
• Go to Advisors tab and fix all reported issues.

Expected behavior

There should be no errors and warnings in advisor.

Screenshots

Additional context

• Most issues will be solved by enabling RLS on table schemas, see https://supabase.com/docs/guides/database/postgres/row-level-security
• Permissive policy allowing access to all (with an API key) is sufficient for now (since we don't support users).
• Fixes must be applied to persistent plugin schema files (e.g. https://github.com/hyperledger/cacti/blob/main/packages/cactus-plugin-persistence-ethereum/src/main/sql/schema.sql) and tested
