connects #2254
This pull request primarily addresses improvements in date parsing for meter data forms and includes minor code cleanups. The most significant changes are focused on how date values are handled when updating meter data, replacing JavaScript Date object parsing with explicit string splitting and parsing. Additionally, there are minor removals of unused code and console logs.

Date parsing improvements:

• Changed the way dates are parsed in both updateElectricityMeterDataFromForm and updateGeneralMeterDataFromForm in utility-meter-data.service.ts to use string splitting and parseInt instead of the JavaScript Date constructor, improving reliability and clarity of date extraction. [1] [2]

Code cleanup:

• Removed an unnecessary console.log statement from the EditBillComponent to clean up debug output.
• Removed an unused import of IdbCustomGWP from edit-electricity-bill.component.ts to tidy up imports.
