* fix(reports): drive report line queries from journal_entries, not the unfiltered lines side
Every report generator fetched journal_entry_lines with a
journal_entries!inner(...) embed and put the tenant filter on the
embedded side (.eq('journal_entries.company_id', ...)). PostgREST
compiles that to a correlated INNER JOIN LATERAL with a parameterized
LIMIT inside, which blocks join reordering: Postgres walked the ENTIRE
journal_entry_lines table (603k rows, all tenants) per report query.
Measured in production: 13.6 s vs 2.7 ms for the equivalent plain join,
against Supabase's 8 s statement_timeout; nightly cloud backups failed
for 5 of 11 companies on 2026-07-09 and a GL report 500'd.
Introduce lib/bookkeeping/entry-lines.ts with a shared two-step fetch:
1. fetch matching journal_entries (id + caller-selected columns)
filtered by company_id / fiscal_period_id / status / entry_date /
source_type, paginated via fetchAllRows;
2. fetch journal_entry_lines with .in('journal_entry_id', chunk) in
chunks of 100 ids (URL-length safety), paginated per chunk;
3. reattach the parent entry to each line under the embed's key shape
(line.journal_entries = {...}, aliasable) and sort lines by id
ascending to preserve the old .order('id') semantics.
Converted call sites (selected columns and filters preserved):
trial-balance (x2), general-ledger, journal-register, sie-export
(reuses its existing entry list via fetchLinesByEntryIds),
vat-declaration, dimension-pnl, opening-balances, monthly-breakdown,
periodisk-sammanstallning, rc-basis-gaps (sibling-line fetch now also
chunked), ar-reconciliation, supplier-reconciliation,
bank-reconciliation, asset-service (x2), bolagsskatt-calculator,
sarskild-loneskatt-calculator.
Tests: unit tests for the helper (chunk size, reattachment shape,
forced id/journal_entry_id columns, empty result, cross-chunk sort,
error propagation); existing report/reconciliation/bokslut test mocks
updated to the two-step query shape, preserving every assertion about
report output.
From the 2026-07-09 production log triage.

* fix(reports): stop echoing raw error messages from the general-ledger route
The catch handler returned err.message to the client in
details.reason; internal error strings (SQL fragments, table names,
timeout messages) must not reach the browser. The error is already
logged server-side with the request id, so the client envelope keeps
only the REPORT_GENERATION_FAILED code.
