Payroll teams can now control the appearance of salary rule lines on printed payslips, including color, bold, italic, and underline styles. This makes payslip formatting easier to adjust directly from salary rules instead of relying on fixed hard-coded presentation.

In this commit, add styling effect on rule to render on printed payslip. Now you are able to change the rule color, bold, underline, italic styling effect dynamically on the rule. Previously, these styling effects had been hard coded.

Subscription lists now include clearer filters that separate automatic payments, manual payments, and automatic invoicing without payment. This helps users quickly understand how each subscription will be billed, while demo data now supports automatic invoice generation by scheduled jobs.

In this PR, added filters to categorize subscription based on payment_token and online_payment values.
- Filter for automatic payments when there is payment token.
- Filter for manual payment when there is no payment token and online payment is require.
- Filter for automatic invoicing without payment when no payment token and online payment is not require.
- rename "Failed Payments" filter to "In Error" for better user understanding
- make online payment false in demo data of subscription so automatic invoice will be generated by cron.

The helpdesk portal grouping option now uses the label "Sales Order Item" instead of "Sales Order". This makes the interface more accurate and avoids confusion, since the grouping already worked at the sales order item level and no behavior has changed.

Renamed the group by field from 'Sales Order' to 'Sales Order Item'. The behavior was not changed as it was already grouping by Sales Order Item.

India payroll salary rules were simplified by removing duplicate entries for salary assignment and attachment. This reduces confusion in payroll configuration while keeping the net salary calculation unchanged.

Currently, the 'Assignment of Salary' and 'Attachment of Salary' rules are duplicated in the salary rules, and the NET formula is the same. I have removed these duplicate rules from the India payroll.
