Customer log: /do/inv/dsave failed with "Error converting data type float to
numeric" followed by "Cannot insert the value NULL into column 'InvId'".
- Bump OCORE: SQL_Float/SQL_Decimal string overloads parsed negatives via the
de-DE server culture ("-19.95" -> -1995); float noise overflowed
numeric(10,3), so fds__setInvoice never ran.
- InvoiceService: the header save batch now stops with a clear THROW when
fds__createInvoice/fds__setInvoice yields no @Id, instead of failing again
in fds__createInvoice_Details and burying the real error. Batch SQL
extracted to BuildRegisterInvoiceSql for testing.
- Tests: signed/culture parsing under de-DE, Storno param build against the
proc numeric limits, and the batch guard ordering.
- hlp: read-only script to find invoice/reminder amounts stored scaled up
by the bug.
