Eliminate O(N*M) linear scans in view assembly.
GetTransactionViewList / GetBookingRuleViewList: precompute
accountsById and use dictionary lookups instead of accountList.Single
per row. GetAccountViewList: group transactions by
TargetAccountId/OriginAccountId once; per-account balance is now O(k)
instead of a full scan. Fold GetBalanceInAccountCurrency and
GetCurrentBalanceInCHF into a single ComputeBalance helper so the
account-currency balance is computed once per account instead of
twice.
Defer item 19 (async I/O): after PR D each XML file is loaded at most
once per circuit, and this app is single-user local Blazor Server, so
async would be ~40 files of churn for negligible benefit.

- Add IMPROVEMENT_PLAN.md with phased plan for follow-up work
- Consolidate DI registrations into a single AddAccounting() extension;
drop the duplicate service registrations and the PdfParsingService
self-registration
- TrySetYear: capture this.year before overwriting so rollback actually
restores the previous value
- DummyFxService: check toCurrency (was checking fromCurrency twice)
- TransactionRepository.GetTransaction: return a copy instead of mutating
the loaded entity, and guard against unknown ids
- ViewService.GetTransactionViewList(accountId): flip the sign on a copy
rather than mutating the entity returned by the repository
- FileService.GetTransactionListCsv: same treatment; use a local
signedValue instead of mutating trx.Value
- ProfitLossReport: use ClassIds.Income/Expenses instead of magic 3/4
- CLAUDE.md: correct the ClassIds documentation (1/2/3/4, not
1000/2000/3000/4000)
SettingsService lifetime is intentionally left as Singleton for now;
making it Scoped requires persisting year/mandator selection across
page reloads first (tracked in the plan).
