fix: skip declined events in tooltip, modeline, and notifications

org-gcal writes `:STATUS: declined' on calendar entries the user has declined,
and chime was happily showing them in the tooltip, modeline, and notification
stream — which defeats the whole point of declining a meeting.

I added `chime-declined-events-predicate', mirroring the shape of
`chime-done-keywords-predicate', and put it on the default
`chime-predicate-blacklist'. The match is on the literal lowercase value
because that's what real org-gcal exports use; uppercase or other values pass
through. Users who want declined events back can pop the predicate off the
blacklist.

Tests cover all four STATUS values seen in real org-gcal data (accepted,
declined, needs-action, tentative), plus the no-property, empty-property,
todo-keyword-still-attached, gibberish-value, case-sensitivity, and
default-blacklist-membership cases.
