Decouple ServerLoggerConnector from connection

[kmcginnes]

Parent PRD

• Parent Simplify client-server relationship by removing proxy URL from connection config #1618

What to build

Update ServerLoggerConnector to use the apiBase constant directly instead of receiving a connection URL in its constructor. Replace createLoggerFromConnection with a connection-independent factory that always creates a ServerLoggerConnector. Logging to the server works even before a connection is configured.

Type: HITL — requires review before completion.

Acceptance criteria

• ServerLoggerConnector constructor takes no arguments, uses apiBase internally
• createLoggerFromConnection is replaced with a simpler factory (no connection dependency)
• Server logging works before any connection is configured
• Tests verify logs are sent to ${apiBase}logger
• Tests verify the logger works without a connection

Blocked by

• Blocked by Create apiBase module and wire client fetch to /api/* #1621
