## Summary
Adds a non-intrusive warning banner in the query editor that alerts
users when the selected time range exceeds 1 year (365 days). This helps
users understand that their query may return a large amount of data and
could take longer to execute, without blocking or interrupting their
workflow.

## Changes
- Added `TIME_RANGE_WARNING_THRESHOLD_DAYS` constant (365 days) in
`src/datasource/constants.ts`
- Created new `TimeRangeWarning` component in
`src/datasource/components/TimeRangeWarning.tsx`
- Integrated the warning component into the main `QueryEditor` component
## How it works
- When the dashboard time range is >= 365 days, a warning banner appears
at the top of the query editor
- The warning displays the formatted duration (e.g., "1 year and 30
days")
- The warning is purely informational - queries still execute normally
- Uses Grafana theme colors for consistent styling in both light and
dark modes
## Screenshot
The warning appears as a subtle banner with a warning icon:

## Why
Queries spanning years of data can return millions of data points and
potentially overload the Zabbix server. This proactive warning helps
users make informed decisions about their query scope without adding
friction to the normal query flow.
## Summary
Adds a non-intrusive warning banner in the query editor that alerts
users when their query matches a large number of items (>= 500). This
helps users understand that their query may return a large amount of
data and suggests using more specific filters.
Part of https://github.com/grafana/oss-big-tent-squad/issues/127
## Changes
- Added `ITEM_COUNT_WARNING_THRESHOLD` constant (500 items) in
`src/datasource/constants.ts`
- Created new `ItemCountWarning` component in
`src/datasource/components/ItemCountWarning.tsx`
- Updated `MetricsQueryEditor` to track and report the count of items
matching the current filter
- Integrated the warning component into the main `QueryEditor` component
## How it works
- When items are loaded for the dropdown in the Metrics query editor,
the component counts how many items match the current item filter
- If using a regex filter like `/.*/`, it applies the regex to count
matching items
- If the count is >= 500, a warning banner appears at the top of the
query editor
- The warning is purely informational - queries still execute normally
- The warning only appears for the "Metrics" query type

## Why
Queries that match thousands of items via wildcard filters (e.g.,
`/.*/`) can return massive amounts of data and potentially overload the
Zabbix server. This proactive warning helps users make informed
decisions about their query scope without adding friction to the normal
query flow.
