Keep the special issues section visible, space the digests intro

Two small presentation fixes.

The calendar page dropped its "Journal Special Issues" heading entirely when
no entry existed, which is the state since f132f6b removed the two unverified
CFPs. With only the conference table left, the page read as if journals
weren't tracked at all rather than as having no open call. The heading now
always renders, carrying a line that says so and why: these journals use
rolling submission, so special issue CFPs are their only dated deadlines.

In the digests list the intro paragraph sat flush against the first card.
PaperMod gives .post-entry a bottom margin only, and .md-content zeroes its
last child's, so nothing supplied the gap — the theme never hits this because
its own .md-content usage sits inside a .post-entry. Added a page-intro class
with a bottom margin matching the card-to-card gap, in the extended stylesheet
rather than the submodule.

Hugo isn't installed here, so the digests spacing is reasoned from the theme
CSS rather than rendered.

 Special issue deadlines appear in three places:
 - **Journal page** — a "Special Issues" table below the journal metadata
-- **Calendar page** — a "Journal Special Issues" table below the conference deadlines
+- **Calendar page** — a "Journal Special Issues" table below the conference deadlines. The heading always renders; with no entries recorded it carries a line saying no call is open, so the page doesn't read as if journals went untracked
 - **FullCalendar grid** — events colored purple (`#7b2cbf`), titled `ACR SI — Title — deadline type`, carrying `cfp_url` in `extendedProps`
 
 Dates use the same `MMM D, YYYY` format as conference deadlines. `notification` additionally accepts month-only precision (`Jan 2027`), which lands on the first of that month in the calendar grid; the tables always print the raw string.
