feat(fusion_accounting_reports): seed trial balance report definition

Adds data/report_trial_balance.xml grouping balances by top-level
account_type prefix (asset, liability, equity, income, expense). Each
group is sign-adjusted so that posted, balanced books sum to ~0 in the
'Total (should be 0)' subtotal -- a quick visual sanity check.

Bumps manifest to 19.0.1.0.7.
