feat(cli): --pretty draws each day as an ASCII box

Aligned columns made the fields legible but the days ran together -- with 365
of them the eye had nothing to catch on. Each day now gets its own box: a
heading carrying the date and the liturgical colour, then the celebration, its
rank and season, and any commemorations, each on its own line.

The box art is pure ASCII, only + - and |, never Unicode box-drawing. That is
the point rather than a limitation: this format exists to be pasted or piped
into a document, a mail or a plain-text ordo, and U+2500 and its relatives
survive that only when every stage agrees about encoding and font. +---+ has
never failed to render anywhere.

readings gets a labelled block, so a citation says what it is instead of being
the second of three bar-separated fields; the OF second reading simply omits
its row on the days without one. rubrics becomes a label/value list. temporal
is the day box minus the sanctoral it does not have.

A blank line separates consecutive boxes -- without it the bottom rule of one
day and the top rule of the next sit adjacent and read as a single doubled
line, which is the same "not distinct enough" this change set out to fix.

Alignment counts UTF-8 code points, not bytes, so "Pen~afort" and "Fremiot"
still line the right edge up at 76 columns; a byte-counting pad shears the box
by one per multi-byte character. Over-long values are truncated with a ~
rather than allowed to overflow, since a box whose right edge does not line up
is worse than a clipped name that the default output still carries in full.

Verified: no ANSI escape reaches a pipe on any of the four commands, and the
default output is byte-identical to installed 1.1.0 across all five.
