Add a configuration option or environment variable to disable per-page time range persistence in SigNoz.

Problem Description

Currently, SigNoz remembers the last-used time range for each page (per-page persistence).

This behaviour causes an issue when

• A user explores data for a long duration (e.g., 30d or 90d) to check patterns.
• They then navigate away from that page or close the browser tab.
• When they return to the same page later, SigNoz automatically reloads that long-duration query again, consuming unnecessary resources and putting load on the database.

This can be especially problematic in production environments where:

• Multiple users access the same dashboards.
• Queries over long durations are costly.
• Dashboards auto-refresh, compounding the issue.

Proposed Solution

Introduce a setting or environment variable such as
DISABLE_TIME_RANGE_PERSISTENCE=true

When enabled

• SigNoz will always load the page with the default time range (e.g. 15m or 1h).
• It will not remember or restore the last-used time range for that page.

Alternatives you've considered

• We have asked teammates to manually reset the time range to 5m before leaving any page but this is error-prone and not reliable.
