Connect dashboard UI to /api/status using fetch()

[hebert87]

Description:
Right now the dashboard is using static EJS values when the page loads. I want to connect it to the /api/status endpoint so the data updates while the app is running.

Tasks:

• Replace static EJS values with live data from the API
• Use fetch() every 2 seconds to pull updates
• Update the DOM for bandwidth, quality, and status without refreshing the page

Outcome:
The dashboard should behave like a live monitoring screen instead of a static page.
