feat: Improve Route53 list views with column-aligned lipgloss styling

[nathanhuh]

Summary

The Route53 zone list and record list views display all information in a single line with the same font color, making it hard to differentiate between fields (name, ID, record count, type, values).

Changes Needed

• Zone list: Column-aligned table with header (NAME, ID, RECORDS, TYPE), zone name highlighted on selection, metadata dimmed
• Record list: Column-aligned with NAME (highlighted), TYPE (orange/accent), VALUE (dimmed), truncated for long values
• Record detail: Dimmed fixed-width labels with accent color for record type

Context

Raised during #13 implementation review. The current DisplayTitle() single-line format is functional but hard to scan visually.
