[Feature]: Re-fetch trace from server when viewing a trace

[SOF3]

Requirement

As a user who maintains a custom storage plugin,
I don't want to fetch the whole trace tree in the search page
due to performance and upstream rate-limit concern.

Problem

Jaeger displays an empty trace when I click into a search item directly. This can be manually resolved by reloading the page or opening it in a new tab.

Proposal

Always call GetTrace when displaying a trace. This is also useful if the trace is still updating during the period betweeen FindTrace and user click.

Add an option to refresh trace periodically during trace view.
