style: remove emojis from AI context formatting and prompts

Replaced emoji indicators with text equivalents for better cross-platform
compatibility and cleaner LLM prompts.

 Analyze the above and report any findings using the structured format. Focus on:
-- Resources showing high utilization or concerning trends (look for ↑ growing indicators)
+- Resources showing high utilization or concerning trends (look for "rising" indicators)
-- Predictions showing resources approaching capacity (look for ⏰ predictions)
+- Predictions showing resources approaching capacity
-- Anomalies flagged as unusual (look for ⚠️ anomalies)
+- Anomalies flagged as unusual in the "ANOMALIES" section
 - Patterns that might indicate problems over time (compare 24h vs 7d trends)
 - Missing backups or stale backup schedules  
 - Unbalanced resource distribution
