Bulk-convert the bible-plan TSV into Matins reading data

Converts all ~369 non-blank rows of the user's own scripture-reading
plan TSV into data/hours/bible-plan/*.yml, mapping each row's day label
to this app's (temporalId, weekday) or Dec25-Jan13 calendarDate scheme.
Fixes a few source TSV typos in the process (chapter-range and
trailing-colon citations); status stays explicitly `missing` pending the
separate Vulgate/Douay-Rheims import.
