Process time-entries in background on submit & reduce timesheet count in recalculation job

[Siddhantsingh1230]

Description

This PR optimizes the timesheet approval process by moving timesheet approval process to the background, reducing frontend wait time. It refactors the weekly status and hourly salary calculation logic to use a unified method that respects employee work schedules. Additional improvements include: reducing job chunk size (2000 → 300), setting job timeout to 1h, fixing a zero float division error in a custom field patch, and resolving word break issues in the text-editor tooltip when hovering over timesheets.

Relevant Technical Choices

• Add a check for total: Return if total is 0
• Conditionally use "break-all" tailwind class to avoid word breaking in TextEditor component
• Update common method to work based on the employee schedule.

Testing Instructions

• Execute the patch using bench execute
• Create long text timesheet (Try this: Debug the child table render issue in webform, Debug child table render issue in webform)
• Hover above the newly created timesheet
• Text Content should not break
