feat(ui): polish plan search and status phone controls

[CodeDotJS]

Summary

• Plan: after picking From, focus moves to To; focusing a field selects all text; on phone, suggestions flip above/below from remaining viewport space
• Status: clear control on the looked-up station card; history day dialog drops line dots, centers the title with year, and uses compact close buttons

Test plan

• Plan: pick From → To focuses; refocus selects all; phone keyboard → suggestions stay visible above or below
• Status: look up or locate a station → clear (X) removes it
• Status: tap a history day → centered title with year; compact close
• Walk /, /status, /saved, /city, /play, /lines, /help
