Reminder alert:
- Dismiss now matches Snooze's full-opacity text color instead of 0.6
alpha, which read as a disabled button.
- Button row inset brought to 20px to match the header/body zone above
it (was 16px, visible as a step across the divider).
Snooze popover:
- Options are left-aligned (each button's label now sets its own
xalign) and span the full row width instead of centering as a
ragged-left stack of labels.
- Added a hairline divider between options so the list reads as
distinct rows even in the popover's static/non-hover state.
- Added a "Custom…" option that reveals a free-form time entry,
reusing the same rule-based time parsing breadman's dialogs use,
instead of only offering the three fixed presets.
- Popover now matches the reminder card's flat-bordered elevation
(no arrow, 1px border, no shadow) instead of GTK's default
arrow+drop-shadow popover chrome.
Compose popup: dropped the bare accent-teal checkmark submit button
(same colour as the selected type pill, unlabeled) in favor of a
"Press Enter to add" hint, since the popup already grabs focus and is
keyboard-driven. Also made the entry's CSS padding uniform (14px on
all sides, was 12px/16px).
