Fleet UI: Fix observer persisting host_id when querying host from host details page

[RachelElysia]

Issue

Cerra #20959

Description

• Bug: Design decision to not allow observers to access edit query page and redirect to query details page caused regression with allowing observers to flow host_id into query flow that starts on edit query page from host details page > query option
• Fix: Since observers are pushed to the query details page when they don't have access to edit query page, persist host_id param on query details page as well, so when user goes to live query flow, the host_id param persists
