Expose per-account number on transactions output

[ItzikEzra]

Problem

The RiseUp API returns a field on every transaction that identifies which physical card or account billed it — Transaction.accountNumberPiiValue (typically a masked identifier — last 4 digits of a card, or an obfuscated account number). The field is already defined in src/client/types.ts, but the CLI never surfaces it in any command output.

The result: riseup transactions currently tells you that the transaction went through "isracard", but not which Isracard. For households with several cards under the same issuer (common for spouses on the same Isracard umbrella, or a single bank with multiple debit cards), this makes it impossible to answer questions like "how much did I spend vs how much did my partner spend?" from the CLI alone.

The data is one field away from being useful.

Fix

Adds an accountNumber field to the output of commands that list individual transactions:

• riseup transactions --json — new optional key, emitted only when tx.accountNumberPiiValue is present
• riseup transactions — new "Account" column in the table
• riseup unclassified --json — same optional key

Aggregate commands (spending, trends, income) are untouched — they already group or total, so per-transaction account numbers don't apply there.

Backwards compatibility

The JSON change is additive and guarded:

...(tx.accountNumberPiiValue ? { accountNumber: tx.accountNumberPiiValue } : {}),

Consumers that parse the JSON without this key keep working. The table gains a column, which is a breaking change for anyone grepping table rows positionally — this seems unlikely but worth flagging.

Why this is the right shape

• The field already exists on the type.
• The semantic matches what source was meant to do — identify where the money came from — but at a finer grain.
• No new API calls, no new types, no new dependencies.
