fix(templates): clear the wall calendar's class label of the border, add sigla

Problem 1: grid.tex's \daycell pushed the rank/class line to the exact
bottom edge of its fixed-height parbox with \vfill, the same edge \hline
draws the cell's bottom rule along, so 'I classis'/'IV classis'/'II
classis' printed as if sliced by the rule. Fixed by nesting a second,
shorter parbox (\cellh minus a new \cellpad, 1.5mm) inside the
unchanged \cellh-tall outer one, so the \vfill only ever reaches to
\cellpad above the rule, never touching it. \strut on both trailing
lines belt-and-suspenders the fix for lines with no descenders.

Problem 2: each cell now also carries the day's Epistle and Gospel
references (view fields first/gospel), joined by a centred dot/bullet
rather than repeated Ep./Ev. labels -- the same compact convention
ordo.tex already uses between rank_name and colour_name. A grid cell is
only ~3.5cm wide and Holy Week's own citations run 20-30 characters each,
so class label and sigla get their own \tiny line apiece rather than
being crammed onto one line and shrunk past readability; \cellh leaves
about eleven \tiny lines of room, so two short lines cost little. Both
first and gospel are wrapped in their own conditional section so a day
missing either prints no stray separator (defensive: every day in the
shipped EF lectionary has both, but nothing guarantees that of a future
rite or overlay).

grid.ms gains the same sigla, on their own .br line, using tbl's existing
w() wrap rather than any manual line-splitting -- it was never subject to
problem 1 (tbl auto-sizes row height, no fixed-height clipping risk) and
never carried a class label to begin with, so none was added here.
grid.html gains the sigla as a small, muted block-level span; unlike the
two paper flavours it isn't boxed onto a fixed physical page, so the
browser just grows the cell rather than needing any line-budget
compromise.

Verified with two pdflatex passes and groff -ms -t -Tpdf against all
twelve 2027 months: zero Overfull warnings, 7 columns every row, class
label and sigla both fully clear of every rule. test/golden/grid-2027.*
regenerated through test_render_golden.ml's own render path (View.of_days
+ Template.render_string, the EN-with-LA-fallback lang table), not the
CLI, per this project's own standing trap about the two tables differing.

+% Border clipping, fixed: the original \daycell put \vfill directly inside
+% the \cellh-tall parbox, so the rank line's own text sat flush against the
+% box's bottom edge -- the identical edge \hline draws the cell's bottom
+% rule along -- and printed as if sliced in half by the rule. The fix
+% keeps the OUTER parbox exactly \cellh tall (every cell in a row must
+% still be identical height, or the table stops being a grid), but nests a
+% SECOND parbox inside it that is only \cellh minus \cellpad tall and
+% carries the actual \vfill. That leaves a strip of \cellpad, genuinely
+% blank, between the last line of content and the rule -- not merely
+% smaller type or a hopeful \strut. \strut on both bottom lines is kept
+% too, belt and suspenders, so a line with no descenders still reserves a
+% descender's worth of depth.
+%
+% Sigla, compactly: each cell also carries the day's Epistle and Gospel
+% references (view fields first/gospel), joined by a centred dot rather
+% than repeating "Ep."/"Ev." labels -- the same choice ordo.tex already
+% made between rank_name and colour_name, kept consistent rather than
+% invented a second way. A cell is only about 3.5cm wide, and Holy Week's
+% own citations run to 20-30 characters each (a Passion narrative spanning
+% several chapters), so "rank_name . first . gospel" does not fit one
+% \tiny line together in the worst case -- measured against the rendered
+% width, not assumed. The rank line and the sigla therefore get their OWN
+% line each rather than being crammed onto one and shrunk past \tiny:
+% \cellh leaves ample vertical room (about eleven \tiny lines per cell),
+% so two short lines cost far less than illegible type would. Both first
+% and gospel are wrapped in their own conditional section (mirroring
+% ordo.tex's own idiom) so a day missing either (there is none in the
+% shipped EF lectionary, but a future rite or overlay is not guaranteed to
+% keep that invariant) prints no stray separator.
