Bill purchase tax is not posted to GL and tax line renders undefined

I can reproduce a Bill/purchase tax posting issue in self-hosted BigCapital. ### Scenario 1. Create a tax rate, e.g. BTW-21 / 21%. 2. Configure a purchase item with cost account = Office expenses and purchase tax = BTW-21. 3. Create a Bill/purchase invoice, tax exclusive, one line for EUR 100 net with that item/tax. ### Actual behavior - Input screen calculates EUR 21 VAT correctly. - Bill details tax line renders as `undefined [[object Object]%]`. - Journal/GL posts only: - Dr Office expenses 100.00 - Cr Accounts Payable 100.00 So VAT is not posted and Accounts Payable is not grossed up to 121.00. ### Expected behavior - Dr Office expenses 100.00 - Dr input VAT / Tax Payable 21.00 - Cr Accounts Payable 121.00 The Bill tax line should also render the tax name/rate correctly. ### Source observation Checked current upstream and latest release `v0.25.20`. In `packages/server/src/modules/Bills/commands/BillsGL.ts`: - `getBillTaxEntry(...)` exists. - `getBillTaxEntries` is commented out. - `getBillGLEntries()` does not include tax entries. In `packages/server/src/modules/Bills/queries/Bill.transformer.ts`: - Bill `taxes` are included, but the tax transformer is commented out. - The web Bill footer expects flattened `name` / `tax_rate` fields, which may explain `undefined
