feat(balance): rewrite snapshot editor reducer for holdings + dispatch on account.kind (#213)

Structural rewrite of useSnapshotEditor for N holdings per detailed account,
and switch ALL simple/detailed dispatch from category_kind to the account's
own kind. This is the state/plumbing layer; the full multi-security entry UI
(SecurityPicker, rich sub-rows) lands in #214. Simple accounts behave
identically.

Reducer state shape:
- values:   Record<accountId, string>        (simple accounts, scalar)
- holdings: Record<accountId, HoldingDraft[]> (detailed accounts, one per title)
HoldingDraft is a string-typed, editable mirror of SnapshotHoldingInput with a
stable client-side rowId for React keys. Actions: ADD_HOLDING / REMOVE_HOLDING /
SET_HOLDING_FIELD (plus existing SET_VALUE/PREFILL/RESET). The legacy priced
scalar path (SET_PRICED_FIELD / pricedValues) is removed: after migration v16
(#211) every former-priced account is kind='detailed' with one holding, so those
accounts flow through the holdings path.

Dispatch:
- LOADED hydrates detailed baskets via listHoldingsBySnapshotLine (edit) keeping
  the saved price, or getHoldingsForLatestSnapshot (new) dropping the price
  (qty-0 excluded server-side). Simple accounts keep the scalar value path.
- SnapshotLineRow / SnapshotEditor / AccountForm now gate on account.kind, not
  category_kind. category.kind survives ONLY as the suggested seed default for a
  NEW account in AccountForm.

Save: detailed accounts pass their holdings array into SnapshotLineInput.holdings
(presence marks the line detailed; value = rounded-cent SUM); simple accounts
pass a scalar value with no holdings. Blank holding rows are skipped; a partial
row throws a typed error before any DB mutation.

AccountForm: adds an entry-mode selector (defaulting to the category-mapped
kind). New accounts persist as 'simple' (CreateBalanceAccountInput carries no
kind, and the service is out of this issue's scope); converting a fresh account
to detailed + pivot date is #215. Editing locks the selector for an already-
detailed account (the detailed->simple downgrade is service-guarded).

Tests: 19 new reducer/helper unit tests (pure exports; the project has no
renderHook harness) covering ADD/REMOVE/SET_HOLDING_FIELD, LOADED-vs-PREFILL
hydration (price drop, book_cost), qty-0 already excluded upstream, the
build*Lines save builders, and the dispatch-on-account.kind regression
(detailed account under a 'simple' category).

Resolves #213.

// Two variants are dispatched by the account's OWN `account.kind` (#213),
// NOT by `category_kind`:
//
// - `simple` (Issue #146): a single value input keyed by `account_id`.
// - `priced` (Issue #140): three inputs — `quantity`, `unit_price` (both
// required), and a read-only `value` field that
// renders `quantity * unit_price` live as the
// user types. An attribution tag `[Manuel]`
// appears next to the row; the `[via Maximus]`
// tag is rendered by PriceFetchControl (Issue #158).
// - `detailed` (Issue #213): N sub-rows, one per security held — each with
// `quantity`, `unit_price` (both required), a read-only live
// `value`, and the existing PriceFetchControl. The account's
// value is the sum across its holdings.
//
// We keep this component dumb on purpose: it receives strings from the
// parent (the editor stores raw strings to preserve partial input) and
// emits new strings on every change. Numeric validation happens at save
// time in `useSnapshotEditor.save` against the service's
// `validateLineKindInvariants` helper.
// The OLD "priced scalar" variant (one security via account.symbol + scalar
// quantity/unit_price on the line) is SUPERSEDED: migration v16 (#211)
// converted every former-priced account into `kind='detailed'` with one
// holding, so those accounts now flow through the detailed (holdings) path.
//
// This PR (#213) keeps the detailed UI deliberately minimal — it must round-
// trip a converted 1-holding account and not crash; the full add/remove +
// SecurityPicker UX lands in #214. The symbol field here is a plain text input
// (the autocomplete picker is #214).
