refactor(epg): hairline dividers, en-dash time, single-line description

Separation: replace 4px gap with hairline dividers via ::before, hidden
around the active and current-program rows so they read as a continuous
emphasized block. Title line-height 1.4 → 1.3 + letter-spacing -0.01em
to match channel-name. Time uses en-dash, 0.78rem (parity with summary
bar), token-driven --app-muted-color. Description clamped to one line —
full text remains one click away via the info icon.
