fix: make pulse-relaxed tag use fixed thresholds instead of additive

changed pulse-relaxed behavior to override with fixed values (95% CPU/RAM, 98% disk) rather than adding to existing thresholds. this avoids confusing interactions with custom alert rules and provides more predictable behavior

also updated docs to clarify the priority order of tags vs custom rules

 #### Available Tags
 - **`pulse-no-alerts`** - Completely disables all alerts for this VM/CT
 - **`pulse-monitor-only`** - Shows in UI but suppresses notifications (email, webhooks)
-- **`pulse-relaxed`** - Increases thresholds (CPU/RAM to 95%, disk to 98%)
+- **`pulse-relaxed`** - Sets thresholds to 95% for CPU/RAM, 98% for disk
+
+#### Priority Order
+Tags take precedence over other configurations:
+1. `pulse-no-alerts` tag - Overrides everything, no alerts at all
+2. `pulse-relaxed` tag - Overrides to 95%/98% regardless of custom rules
+3. Custom Alert Rules from UI - Applied if no tags present
+4. Default global thresholds - Used if nothing else is configured
+
+**Note:** `pulse-monitor-only` works with any threshold source. Tags are checked every 30-60 seconds, no restart needed.
 
 #### How to Use
 1. In Proxmox, edit your VM/CT
