Design polish of the Runtime tab's connector tables; no issue.

Describe Manual Test Plan

Compared the Tables (inputs) and Views (outputs) connector tables before and after this change, in light and dark mode, with three datasets: a six-table pipeline with transactions, a multi-connector pipeline with an unhealthy connector, and an edge-case set covering every connector state (running, ingesting, paused, end of input, parse/transport/encode errors, fatal error, checkpoint barrier, unhealthy with and without a description, no latency yet, 999,999,999-sized values, long connector names, mixed multi-connector rows).

Checked that:

• every header reads as two lines (family / unit), and the Latency p99 tooltip opens and is left-aligned;
• columns of one metric family sit together and each family starts after a wider gap; number columns keep their width as values change;
• the unhealthy warning icon hangs before the status icons, so status icons stay aligned on every row, and clicking it opens the description popover with the copy button;
• the expand chevron points right when collapsed and down when expanded, and expandable rows have a visible hover in both themes;
• error counts still open the matching connector errors.

bun run check passes (0 errors). ConnectorMetricsTables.svelte.spec.ts passes (41/41). The full test-unit run has a few click timeouts that differ between runs, and plain main shows the same on this machine.

Screenshots: before/after posted as a comment below.
