Inconsistent amount formatting in CSV output when using `--budget`

[profmaad]

hledger seems to be inconsistent in how it formats amounts in the CSV output of a budget report, based on whether --budget is passed or not.

hledger version: hledger 1.51.2, linux-x86_64

Sample journal:

commodity EUR 1,000.00

~ monthly
    (Expenses:Example)                    EUR 100000

2026-01-02 Bug report
	Assets:Example  EUR -42000
	Expenses:Example

hledger balance without --budget ignores the commodity formatting directive (I would say correctly):

$ hledger -f bug_report.ledger balance -b 2026-01-01 Expenses -O csv
"account","balance"
"Expenses:Example","EUR 42000.00"
"Total:","EUR 42000.00"

But hledger balance with --budget prints the amounts as per the commodity formatting directive, thus breaking CSV parsing of the output:

$ hledger -f bug_report.ledger balance -b 2026-01-01 Expenses -O csv --budget
"Account","2026-01-01..2026-01-02","budget"
"Expenses:Example","EUR 42,000.00","EUR 100,000.00"
"Total:","EUR 42,000.00","EUR 100,000.00"

Thanks for the report. I agree, csv output should always be showing machine-friendly numbers.
