This update enhances Odoo's database performance by introducing SQL aliases across various models and reports. Using aliases simplifies complex SQL queries, leading to faster data retrieval and improved system responsiveness. This change primarily focuses on internal optimizations within the database layer.

This update restricts the number of attendees displayed in email invitations to a maximum of 20 to prevent overly long lists. When more than 20 attendees are invited, the email will indicate '… and X more’ to manage communication clarity. This improves email readability and reduces potential issues with large attendee counts.

In order to avoid extremely long attendee lists, which can
sometimes have hundreds of entries, limit the number of
attendees shown in the various calendar.event and
calendar.attendee mail templates to a maximum of 20.

If more than 20, add '... and X more' where X is the number
of attendees left beyond the displayed 20.
