This update improves how the Indian GST reports module retrieves a specific return status field. The change is internal and should make the related process slightly more efficient and easier to maintain without changing user workflows.

In this PR:
- Replaced the `search` method with `_get` to directly fetch the `gstr1_status` field from `l10n_in.gst.return.period`, improving efficiency and readability.

Activity summaries on accounting dashboards are now shorter by removing deadline text that already appears on the activity itself. Some activity messages were refined, and the generic tax payment reminder was removed except where it remains relevant for Belgian reporting.

We're removing the "deadline" from the activity summary as the actual deadline on the activity record is enough for the users to know when it is due. This also makes the activity look more concise and easier to read on the dashboard.

This commit also makes minor adjustments to the
summary messages and removes the "pay tax" activity since it's irrelevant. We'll keep that activity for l10n_be only.
