Summary

• .rl becomes flex: 0 1 auto with margin-inline-end: auto and no white-space: nowrap, so a settings label takes its natural width and wraps only when it alone is wider than the row.
• .rv becomes flex: 1 1 0, so the value takes the remaining space and is the part that ellipsizes.
• Buttons and switches in rows without a value stay at the trailing edge.
• Remove the .kv-hdr .rl override, now the default.

Testing
All green, e2e included. On 47 admin rows at 390 px no label is cut (was 2, "Allowed Addresses" among them) and no trailing control moved.

Changelog

Fixed

• Show settings labels in full on a phone instead of cutting them off.

Checklist

• Stays within the project constraints: one container, no runtime dependencies, no build step (see CONTRIBUTING.md).
• Tests added or updated for new logic, and the full suite, lint, and typechecks pass.
• Docs updated if behavior or configuration changed.
