## What kind of change does this PR introduce?
This is a first draft at introducing semantic colours to our
Observability charts. This moves away from just random colours being
assigned to prop after prop. They're only scoped to the Database reports
right now, but if it flows nice, we can open it up to the other reports
too.
This also aims to tone down some of the harsher colours in our charts,
such as the orange which sometimes can look like a warning metric/prop.

## What kind of change does this PR introduce?
This fixes the following:
- Our `<MetricCard />` and `<LogsBarChart />` which use `<ChartTitle />`
were rendering the wrong font style for the title. The `font-mono` class
being overwritten by recent changes, this helps sort cascade so it
renders correct.
- In our design system, the warning variable for charts was rendering
black, this should be fixed to be our warning yellow.
- There was an odd padding on `<MetricsCard />` content area, meaning
our line chart wasn't flush to the edges, this required a small
extension to `twMerge` so it could resolve.
Please have a look around studio in places we have charts to double
check nothing is broken. Also compare live design system vs. this branch
by checking Logs Bar Chart, Charts and Metrics Card pages.
