Subject: [PATCH] fix(api): handle null/None values in API parsing

Added safe_decimal() helper to handle None/empty values from API
that were causing decimal.ConversionSyntax errors.

Fixed parsers:
- NexusHealingTool: Uses safe_decimal for decay/heal amounts
- NexusRing: Uses safe_decimal for max_tt/min_tt
- NexusClothing: Safely handles None buff values

Errors were occurring when API returned null for numeric fields
instead of 0.
