Replaced the manual useState(data/loading/error) + load useCallback + useEffect
(and the R3 request-seq guard) with a useAnalyticsSummary(params) query hook.
React Query now handles caching, dedup, cancellation, and out-of-order responses
via the params-encoded key; keepPreviousData keeps the last result visible while
a new month/filter loads. Refresh -> refetch; the redundant page-load error toast
is dropped in favor of the existing inline error state.

The month/filter-driven loaders on Analytics, Summary, and Spending (x2)
fetched + setState with no race guard, so a slow response for old params could
overwrite fresher data (or setState after unmount) on rapid month/category nav.
Added the request-sequence guard already used by the Bank ledger (newest
request wins; stale ignored). Bills/Subscriptions load once ([] deps) so they
weren't at risk; BankTransactions already had the guard.

The client had ~15 hand-rolled currency formatters (local `fmt`/`money`/
`fmtFull`/`fmtDollars`/…) plus a canonical `fmt` in lib/utils used at ~190
sites — same rules copy-pasted, with inconsistent handling of negatives,
whole-dollar, cents vs dollars, and blank input.
Add client/lib/money.js as the one implementation:
- formatUSD(dollars) — "$1,234.56" (whole/dash options)
- formatUSDWhole(dollars) — "$1,235"
- formatCentsUSD(cents) — from integer cents; signed "+/-" and dash options
Inputs are coerced so null/''/NaN never render as "$NaN", and -0 is
normalized so it never shows as "-$0.00".
lib/utils.fmt now delegates to formatUSD (byte-identical — the existing
utils.test.js fmt suite is the regression guard), and the 15 local
formatters delegate to money.js. No display currency formatting remains
outside money.js; the /100 conversions left behind are calculations
(form prefill), not display.
Tests: client/lib/money.test.js (13). Full client suite 46 pass; build clean.
