fix: correct jakim_code for 4 districts in Perak and Sarawak

Cross-referenced jakim_code values against official JAKIM zone-district
mapping from the Takwim Solat reference document:
https://www.e-solat.gov.my/index.php?siteId=24&pageId=43
and JAKIM e-Solat API (https://www.e-solat.gov.my)

Fixes:
- Kerian (Perak): PRK01 → PRK06
- Kinta (Perak): PRK01 → PRK02
- Hilir Perak (Perak): PRK02 → PRK05
- Bukit Mabong (Sarawak): SWK03 → SWK04
