* chore(sql): add LAG examples for time-based value comparisons
Enhance window function documentation with practical examples for
calculating differences between current and previous values (e.g., 1h ago).
- Add 3 LAG examples to window functions reference with tested queries
- Create new 'Compare values' query guide covering common time-based
comparison patterns (differences, percentage changes, exact intervals)
- Add guide frontmatter for all InfluxDB 3 products
All queries validated against InfluxDB 3 Core.

* chore(sql): add counter metrics examples to compare-values guide
Enhance time-based value comparisons with counter metrics patterns
using LAG and GREATEST to handle counter resets.
- Add counter metrics section with 3 examples (rate, cumulative, intervals)
- Include tested queries for non-negative differences and aggregation
- Document workarounds for Flux increase() and InfluxQL NON_NEGATIVE_DIFFERENCE()
All queries validated against InfluxDB 3 Core.
