fix(frontend): clarify channel period timeline

[riderx]

Summary (AI generated)

• replace the selected-period cards with a clearer start / latest / movement timeline
• remove the percentage-points presentation that made the adoption cards harder to interpret
• make the 1-day filter compare today versus yesterday instead of showing a single day only

Motivation (AI generated)

After the first channel adoption PR, the selected-period cards were still easy to misread. Users could see 100% in the latest snapshot while the period-start card showed 0%, and the use of points versus percentages made that look inconsistent instead of chronological.

Business Impact (AI generated)

This makes Capgo's rollout analytics easier to trust and reduces customer confusion on a key update-adoption page, which should lower support overhead and improve confidence in the dashboard.

Test Plan (AI generated)

• Open channel statistics and verify the selected-period row reads as start, latest, and movement across the range
• Select 1 day and verify the UI says Today vs yesterday while the chart shows two points
• Confirm the latest snapshot cards remain unchanged and still match the status banner
• Note: automated validation was limited in this worktree because repo-local eslint and vue-tsc are not installed

📝 Walkthrough

Walkthrough

Updates localization and UI copy to describe adoption as a range (start → latest) instead of point/peak comparisons; refactors the statistics Vue component to use range formatting and simplified period logic; removes email from a cron email payload/logs in a Supabase trigger.

Changes

Cohort / File(s)	Summary
Translation keys messages/en.json	Removed keys referencing period-start/peak (adoption-at-period-start, best-day-in-period, points-short, etc.); added range-focused keys (adoption-over-selected-period, today-vs-yesterday, latest-day-in-selected-period, start-of-selected-period) and adjusted channel-stats-period-help.
Statistics component (UI & logic) src/pages/app/[app].channel.[channel].statistics.vue	Replaced formatSignedPoints() with formatPercentRange(); introduced requestedDays mapping and today-vs-yesterday label for 1-day views; simplified periodSummary (removed peak computation) and updated the three overview cards to show start-of-period, latest-day, and adoption-over-selected-period with new translation keys and adjusted display/conditional styling.
Backend trigger (cron email) supabase/functions/_backend/triggers/cron_email.ts	Removed email from the payload passed to handleDailyFailRatio and removed email from two error log metadata entries; control flow unchanged.

Poem

🐰 I hopped through keys and charts today,
Swapped peaks for ranges, start→latest play,
Removed a stray email on the way,
Cleaner cards now lead the display—
Little changes, big bright day ✨
