test: relax memory size assertions in RelationalDatabase_test

Browse Source 
- Replace exact KB values with reasonable ranges
- RWDB: Check starts at 0, increases with data, maintains relationships
- SQLite: Check non-negative values and non-decreasing behavior
- Both: Focus on testing relationships rather than brittle exact values
