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.

Remove the settings-mutating year-hopping in GetAccountExpensesPerMonth
that discarded the user's header year selection and silently forced
the Spendings-over-time chart back to DateTime.Now.Year. The chart
now honours settingsService.GetYear(), skips accounts with no
transactions instead of returning null, and no longer depends on
IAccountRepository or ISubclassRepository.
Also reorder the plan: async becomes PR F, tests PR G.

- Consolidate decimal.ToFormattedString into Schaad.Accounting.Formatting
- Rename EnsureFileExisits -> EnsureFileExists and
SplitPredefiniton* -> SplitPredefinition* (class, interface, files, DI reg)
- AccountRepository: single-save year-rollover start-balance seed
- Drop legacy .NET Standard packages redundant on net9.0 and the stale
Interfaces\Extensions\ folder entry
- Set culture via RequestLocalizationOptions middleware
- Plan: item 9 (unit of work) split off into a dedicated PR D

- 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).
