Ten routes accepted requests with no getCurrentUser check (transactions/[id],
bulk, splits, tags-on-tx, splits/settle, statements/[id], tags, tags/[id],
merchants, participants/[id]/balance), and by-id routes did no ownership
check at all — any participant could read or modify another's data.
Adds canAccessTransactions() (owner via statement/direct, or split
participant), applies it to every transaction-scoped route, owner-scopes
statements/[id], and rescopes splits/settle in raw SQL so settlement only
touches splits the caller is party to.
Also: all trip analytics now sum COALESCE(amount_aud, amount) instead of raw
amount, matching every other analytics query — trip totals previously added
foreign-currency amounts to AUD ones unit-less.
And rules apply_split no longer delete+reinserts splits (which reset settled
flags on every run) — it upserts share_percent and removes only participants
no longer in the rule.
