feat: add `client.query(q.PANEL)` API to retrieve panel details

[palazzem]

Related Issues

• Closes #139

Proposed Changes:

This PR introduces two changes:

1. When calling client.auth() (/api/login), the client stores the response that includes the panel details
2. client.query(q.PANEL) returns the panel details response that is cached after the first call

Query Example

client.query(q.PANEL)

Authenticate the client and call the query method:

client.auth("username", "password")
client.query(q.PANEL)
