fix(studio): cap errors-since-last-deploy log range to 24h DEBUG-173 (#47911)

## Problem

The edge function overview's "Errors since last deploy" panel queried
ClickHouse from the deploy timestamp to now, with no upper bound. When a
function had not been redeployed in a long time, this produced an
unbounded query range, which is suspected to have caused a recent uptime
incident.

## Fix

`getSinceLastDeployLogRange` now clamps the query start to at most 24
hours before now, shared by all three queries this panel issues
(invocation list, invocation count, runtime logs). The section title was
also updated from "Errors since last deploy" to "Errors in the last 24h"
to reflect the new bound.

## How to test

- Open an edge function's overview page for a function that was deployed
more than 24 hours ago
- Confirm the "Errors in the last 24h" panel loads without an
excessively large query range
- Expected result: the panel only queries the last 24 hours of logs
regardless of how old the last deploy was
- Run `pnpm test:studio -- EdgeFunctionRecentErrors.utils` and confirm
the range-clamping tests pass
