* fix(reports): generate valid two-file NE-bilaga SRU submission (#318, #319)
The NE-bilaga "Ladda ner SRU" export produced a file Skatteverket rejects: it
was served as UTF-8 text/plain (å/ä/ö mojibake, #319) and was structurally
invalid — a single blob with #PRODUKT KONTROLLUPPGIFTER (the KU code), no
INFO.SRU/BLANKETTER.SRU split, a #SKAPAT typo, no #FIL_SLUT, and suspect field
codes 7310–7350 (#318).
Rewrite the generator to mirror the working INK2 generator: a two-file
INFO.SRU + BLANKETTER.SRU submission, ISO 8859-1 encoded and zipped, with
#PRODUKT SRU, #DATABESKRIVNING_*/#MEDIELEV_*, #BLANKETT NE-<år>P<x>,
#IDENTITET <personnummer12> <date> <time>, and #FIL_SLUT. Field codes use the
authoritative BAS NE_EJ_K1 coupling table (R1→7400 … R10→7505, R11→7440;
period dates 7011/7012). Enskild-firma identity is the owner's 12-digit
personnummer (birth-century prefix, not INK2's juridisk-person "16").
- Extract the shared ISO-8859-1 encoder to lib/reports/sru-encoding.ts (was
inline in the INK2 route).
- Extend the NE engine/types to carry address/postort/email for INFO.SRU.
- Frontend: NE SRU download uses the INK2 blob pattern; fix a pre-existing
param bug in EfDeclarationSection (fiscal_period_id → period_id, +format=sru).
- Add generator tests (structure, BAS field codes, zero-omission, ISO-8859-1).

* fix(reports): address review feedback on NE-bilaga SRU generator (#318)
- getZipFilename uses the income year (fiscal year END) so the filename matches
the blankett type/identity for broken fiscal years.
- Refuse to generate a submission when the personnummer is missing/invalid
(compute + validate the 12-digit identity once in generateNESRUSubmission and
throw) instead of silently emitting a placeholder #IDENTITET that Skatteverket
would reject after upload.
- validateBlanketterSru now asserts the mandatory räkenskapsår date fields
(#UPPGIFT 7011/7012) — their absence is a level-2 rejection.
- 10-digit personnummer century is inferred from adult age (≥18, <110) at the
income year, fixing the e.g. 1924-born/yy=24 edge that mapped to 2024.
