- Show created_at as "Imported" column in transactions and shared views
- For reconciled transactions, show original CSV import date (not statement processing date) via LEFT JOIN on reconciled_with_id
- Add has_split filter (all/split only/unsplit only) to transactions page
- Transactions table: sortable by imported date; split filter dropdown
- Shared table: client-side sort by date, imported, and amount
Participant id=1 was named "Me" in the DB, causing Sonu and other users
to see "Me" referring to Siddharth when viewing splits and shared expenses.
- Rename participant id=1 from "Me" to "Siddharth" in the DB
- /api/participants now substitutes "Me" for whichever participant matches
the current user, so the label is always relative to the viewer
- split-modal: default split uses currentUser.id instead of name === "Me"
- transactions/page: filter and display logic uses participant ID not name
- shared/page: split chips show "Me" when participant_id === current user
Also includes add-transaction-modal tags support (pre-existing staged change).
- New split_payments table records actual payments between participants
- Balance = total split obligations - total payments (splits never marked settled)
- Record Payment modal per participant: direction toggle, amount pre-filled with balance, date, notes
- Payment history inline on each balance card with +/- display and delete
- Per-transaction Settle button removed; Action column removed from shared table
- Splits always show the true cost breakdown regardless of payment state
- Rewrite participant balance to UNION both directions (they owe me + I owe them)
- Credits/refunds subtract from owed amount for correct net balance
- Allow secondary users to see transactions split with them
- Add participant balance cards with colour-coded owe direction
- Add inline AddParticipantForm with name + optional email
