docs: put the UI review's priorities 1-4 on the board, and correct two claims

The review was written 2026-07-26 and last touched 2026-07-29, one day before
the board replaced ACTIONS.md, so it was never migrated. Priorities 1-4 existed
only in this file. They are now epic #154 with #155-#159 under it.

Two claims in the doc were wrong. It said Priority 0 was guarded by
analytics-sql.test.ts; that file covers the three SQL fragments and nothing
else, so items 2, 3 and 6 -- pace/headline parity, the fees date range, and
partial-month comparison -- have no test at all. Those are the three where a
regression is silent, which is why the gap is worth a ticket rather than a note.

And it predated two changes in the same metric-integrity family: the signed
investments line (c70d2b1) and transfers hidden by default (f6c500b). The first
matters to the doc directly -- the cashflow strip it describes now carries a
signed invested figure, so a negative month is data rather than a bug.

+- **The investments line is signed** (`c70d2b1`, 2026-07-31). `INVESTMENT_SIGNED`
+  makes credits and refunds negative so a withdrawal nets against contributions
+  instead of reading as more money invested. March 2026 had shown $38,615.34 of
+  investing in a month that was net **−$11,384.66**. Consequence for the
+  Analytics section below: the "income, expenses, invested, and net-cash strip"
+  it describes now carries a *signed* invested figure, and a net-disinvesting
+  month is real data — the budget page gates on `!== 0`, not `> 0`.
+- **Transfers hidden by default in the transactions view** (`f6c500b`,
+  2026-07-30), with an explicit category pick overriding the exclusion and the
+  default off when scoped to a statement. An IA change in this review's
+  territory that this review did not propose.
