## Problem
The Report Blocks section (custom dashboards) has four visual and UX
bugs: tooltip content overflows its container, Y-axis labels with 5+
digits get clipped (e.g. `10000` renders as `0000`), action buttons
become unreachable when a block title is long, and scrolling inside a
scrollable block also scrolls the parent page.
## Fix
- Remove the fixed `w-[200px]` class from `ChartTooltipContent` in
`ChartBlock` so tooltips auto-size to their content instead of
overflowing.
- Compute a dynamic Y-axis width in `ChartBlock` based on the string
length of the maximum data value, replacing the `undefined` default that
caused clipping.
- Add `min-w-0` to the label container and `shrink-0` to the actions
container in `ReportBlockContainer` so the truncation works correctly
and action buttons are never pushed off-screen.
- Add `overscroll-contain` to the scrollable SQL code and results table
divs in `QueryBlock` to stop scroll events from propagating to the page.
## How to test
- Navigate to a custom Report with multiple blocks
- Hover over a chart bar on a block with a long metric name. The tooltip
should be fully visible with no text overflow.
- Find or create a block whose Y-axis values exceed 9999 (e.g. disk
IOPS). The full number should appear on the Y-axis without any leading
digits being clipped.
- Use a block on a read replica so the label appends "of replica",
making it long. The chart-type toggle, log scale toggle, and remove
buttons should all remain visible and clickable.
- Add a SQL snippet block that returns a large table of results. Scroll
within the results table. The page should not scroll while the inner
table is scrolling.

## Summary by CodeRabbit
* **Style**
* More consistent Y-axis sizing with dynamic widths for better label
fit.
* Improved Y-axis number formatting (K/M suffixes, sensible decimals)
for clearer tick labels.
* Simplified, more flexible chart tooltips (min-width applied; removed
fixed widths).
* Tighter report header layout so labels truncate predictably and
actions keep their size.
* Added overscroll containment to query results and SQL view to reduce
unwanted scrolling.
