perf(reference-data): sweep the remaining raw reads onto the session cache, ratchet to 0 (#1941)

Final consumer migration of the responsiveness plan: the 35 files still
fetching fiscal periods, settings, accounts, cash accounts, dimensions or
templates on their own now read lib/reference-data, and every client
write site invalidates the shared cache instead of refetching locally.

Settings and registries: FiscalYearsManager, FiscalPeriodEditor (period
snapshotted once per company so a revalidation cannot reset dates being
edited), BookingTemplatesPanel, ChartOfAccounts, ChartOfAccountsManager,
EditAccountDialog, CorrectionEntryDialog, StrikeLinesDialog,
InvoicePaymentAccountsSettings; the dimensions registry (DimensionsManager,
DimensionCombobox, LineDimensionFields, DimensionFilter, bookkeeping/[id])
reads useDimensions and the ad-hoc fetchDimensions/fetchDimensionsCached
helpers are deleted.

Pages and pickers: CashAccountSelector (FyPicker-shaped restore, once per
company load), use-account-names, FiscalYearGapNotice,
OpeningBalancePeriodStep, BankFileConfirmStep, ImportReviewStep, the import
page (invalidates accounts + periods after a SIE execute), customers list,
invoices list + detail, pending, salary employee, asset dispose, year-end
and periodisering pages (invalidate periods after closing), reports
DimensionPnlView (its pivot picker read the wrong payload key and was
always empty; it now populates), SkatteverketPanel, TemplatePicker,
ArticleForm (vat_registered).

Invoice dialogs and extensions: SendInvoiceDialog, PaymentBookingDialog
(init reduced to the credit-note lookup + catalogue, proposal and voucher
preview fire on open when cached; a local getSession replaces the network
getUser for the fallback CC), InvoiceInboxWorkspace, TicWorkspace,
ArcimMigrationWorkspace (invalidates after each SIE import step),
enable-banking AccountPickerDialog.

raw-reference-fetch ratchet: 35 -> 0 files.
