Fix invalid clock glyph in time notification

[stefanomainardi]

Summary

Fixes the "invalid icon" rendered for the Show time notification (SUPER + CTRL + ALT + T) reported in #5776.

Root cause

bin/omarchy-notification-time passed -g <U+F43A> to omarchy-notification-send. That codepoint is in the Nerd Font legacy MDI range (3-byte UTF-8, EF 90 BA). The mako default font=sans-serif 14px does not reliably fall through to a Nerd Font for PUA characters in that range, so the glyph renders as a blank box / tofu.

Every other glyph used by omarchy notifications lives in the modern MDI range (4-byte UTF-8, U+F0000–U+F1AB9). Examples already in tree:

Glyph	Codepoint	Name	Used in
󰍹	U+F0379	nf-md-monitor	omarchy-hyprland-monitor-internal
󱂬	U+F30AC	nf-md-monitor_dashboard	omarchy-hyprland-workspace-layout-toggle
󰴑	U+F0D11	nf-md-content_paste	omarchy-capture-text-extraction
󱫖	U+F1AD6	nf-md-sleep_off	omarchy-toggle-idle
󰂛	U+F009B	nf-md-bell_off_outline	omarchy-toggle-notification-silencing
󱐋	U+F340B	nf-md-flash	omarchy-battery-monitor

The time notification was the only outlier on the legacy range — making it the only one that fails to render on a stock mako setup.

Change

-omarchy-notification-send -g  -u low "$(date +"%A %H:%M  ·  %d %B %Y  ·  Week %V")"
+omarchy-notification-send -g 󰅐 -u low "$(date +"%A %H:%M  ·  %d %B %Y  ·  Week %V")"

󰅐 is nf-md-clock-outline (U+F0150) — same MDI family used elsewhere.

Note for master backport

The same buggy glyph exists on master in default/hypr/bindings/utilities.conf:55 (inline notify-send call). If you'd like the fix backported there too, happy to open a follow-up PR — just say the word.

Test plan

• bash -n bin/omarchy-notification-time — syntax clean
• Verified omarchy-notification-send -g <glyph> accepts the new value (script signature unchanged)
• Confirmed JetBrainsMono Nerd Font (omarchy default) ships U+F0150 (fc-match -s :charset=F0150)
