feat(android): restore MY READING analytics screen

Reintroduces the full reading-analytics UI (streaks, 14-day activity
chart, habits, testament coverage, most-read books, hot chapters,
weekly/monthly/yearly counts, longevity, read completion) that commit
12b578e replaced with a placeholder during the scraper build-fix saga.

The supporting data layer was kept intact by that commit (BibleManager
delegates, ReadingAnalyticsDao, ReadingStats, ConfirmActionDialog/
StatItemCompact), and the unresolved references that forced the gutting
have since been fixed by later refactors -- verified against the current
APIs. All 213 unit tests pass, including the scraper suite.

No scraper code touched.
