feat(dimensions): PR4 reports — dimension-filtered P&L + Resultat per projekt/kostnadsställe (#862)

* feat(dimensions): PR4 reports — dimension-filtered P&L everywhere + Resultat per projekt/kostnadsställe

The Project P&L milestone of the dimensions plan (dev_docs §7 PR4).

One choke point lights up everything: generateTrialBalance gains
options.dimensions (SIE dim → code map) pushed down as jsonb containment
(dimensions @>, served by idx_jel_dimensions_gin) on both line queries, with
company-wide opening balances dropped when filtered (they cannot be
dimension-scoped; P&L-safe by whitelist). Resultatrapport, resultaträkning,
huvudbok, monthly-breakdown and the TB drill-down inherit the filter; the
KPI route filters only its P&L-side inputs (income statement, months,
expense composition) — never cash/VAT.

New report lib/reports/dimension-pnl.ts — "Resultat per projekt/
kostnadsställe" (Fortnox Resultatrapport projekt): value-as-column matrix
over one dimension with an explicit "(Utan dimension)" bucket computed as
the residual against the same trial-balance pass resultatrapport uses, so
every row and the Totalt column reconcile with the unfiltered
resultatrapport by construction. Registered in REPORT_CATALOG (visible only
when dimensions_enabled), slug-routed view + xlsx export.

UI: DimensionFilter (dimension + value picker, persistent "Filtrerad — ej
fullständig rapport" chip) mounts in FocusedReport for catalog entries
flagged dimensions: true; huvudbok rows show line dim codes.

Statutory exclusion pinned by TEST, not convention:
lib/reports/__tests__/dimension-statutory-guard.test.ts fails if the filter
parser leaks into balance sheet, balansrapport, kassaflöde, VAT, SIE or
full-archive routes/generators, or if the catalog whitelist widens.

MCP: new gnubok_get_dimension_pnl (reports:read); dimensions filter arg on
get_trial_balance/get_income_statement/get_general_ledger with
resolve-don't-select (names → registry codes, resolution echoes);
query_journal totals fixed to aggregate the FULL match set (was silently
slice-scoped while claiming otherwise) with an honest totals_scope field,
plus group_by / group_by_dimension aggregation.

Also: voucher-detail dim-6 badge now uses the registry name instead of the
non-standard "PR" abbreviation (#859 review follow-up).

* fix(dimensions): address #862 review — export disclosure, prior-column suppression, period-label honesty, route hardening

- Filtered XLSX/PDF exports now carry the partial-view disclosure past the
  file boundary (BFNAR 2013:2): filename suffix (-dim6-p001), a
  "Filtrerad … — ej fullständig rapport" row on every sheet, and a header
  note/title line in the PDFs.
- Resultatrapport drops the prior-year column when a dimension filter is
  active — project codes are time-limited under K2/K3, so "this code last
  year" may be a different project (same rule as narrowed date ranges).
- dimension-pnl no longer accepts fromDate: the matrix is cumulative from
  period_start by design (closing-balance semantics), and the period label
  now states exactly that instead of echoing a lower bound that was never
  applied. Routes/MCP tool updated to toDate-only.
- dimension-pnl routes 404 on an unknown/foreign period id and cap dim_no
  to 4 digits (matching the MCP tool's PostgREST-path guard, which the
  generator now also enforces itself).
- Statutory-guard test's generateTrialBalance call-site scan is paren-aware
  instead of a 300-char window; added fully-untagged and injection-guard
  test cases.
