feat: the redesigned Event Clock

The new reader app replaces the old UI: Checklist with a rail (focus
pills, Next to expire, today's dailies, pinned routines), Timeline in a
new and a classic look, Routines, Archive and a Settings area, in a
Structured (default) and a Relaxed interface. It follows the approved
Round 6 B and Round 7 mockups, corrected screen by screen with the owner.

Reader data moves to a v2 store (gacha-tracker:v2:*). Existing v1 data
is migrated on first load, a recovery copy is written first, and the v1
keys are never removed, so a rollback finds them unchanged. Redeem codes
for Genshin arrive as their own feed.

Also: live's urgency ramp, editable per theme; completion and
section-complete fireworks; a returning-user tour; the design mockups,
specs, plans, reviews and handoff record.
