feat: separate sub-module workspaces & dashboards

[ruchamahabal]

There are too many sub-modules in HR & Payroll making the navigation overwhelming. A single dashboard for HR having disconnected metrics with no relation doesn't help much (in most companies different HR functions lie with different departments). Add separate dashboards for every sub-module

New Calculated Metrics

Applicant to Hire Percentage

Of all the job applicants, what percentage of applicants are hired?

Job Offer Acceptance Rate

Of all the job offers sent, what percentage of offers are accepted?

Hiring vs Attrition Count

A chart to display month-on-month hiring vs attrition count (source DOJ and Relieving Date of Employee master)

Employees by Age

A chart to display age ranges and the number of employees within each range to get an idea of the workforce demographics. This is calculated based on DOJ in employee master.

Separate Workspaces & Dashboards for each sub-module
