sync: pull progress gradient fills and SLA banner from web_template v1.2

Progress bars now use linear-gradient fills for a more dramatic terminal
readout appearance (matches web_template 39862fa):
- Default (orange), --cyan, --green, --red variants all upgraded from flat
  accent colors to directional gradients with highlight endpoints

SLA banner component (lt-sla-p1 / lt-sla-p2) added to base.css, replacing
the lt-alert workaround previously used for P1/P2 SLA display:
- lt-sla-p1: pulsing red banner (animation: lt-sla-pulse 2s)
- lt-sla-p2: static amber banner
- Subcomponents: icon, info, title, bar, fill, meta, dismiss
- Both fills use gradients for visual consistency (P2 amber→#ffd740)
- lt-sla-dismiss includes transition + :focus-visible ring
