Fix inline edit not updating pricing breakdown on Job Details

Jobs/PatchItem now returns the full breakdown (itemsSubtotal,
subtotalBeforeDiscount, subtotalAfterDiscount, taxAmount) so all rows
in the pricing card update live without a page refresh.

Added data-pb attributes to the matching spans in the pricing panel.
Updated window.inlineItemEdit.totals config for jobs to map each
response key to its DOM selector.

updateTotals in inline-item-edit.js is now fully generic — cfg.totals
keys must match server response property names directly, eliminating
the old hardcoded tax/taxAmount and balance/balanceDue mismatches.
Updated Quote and Invoice configs accordingly (tax→taxAmount,
balance→balanceDue).
