Saving a sequence as a template now checks it's worth saving

When you save a sequence as a template, Botdog now runs a few quick checks to make sure it is useful and different from templates that already exist.
What changed
A template must include at least one meaningful action, such as:
- Sending a message
- Sending a connection invitation
- Reacting to a post
A sequence that only visits a profile, with no follow-up action, cannot be saved as a template.
Botdog will also prevent you from saving a duplicate. This includes sequences that are:
- Identical to an existing template
- Built with the same steps as an existing template, even when the wording is different or left blank
When a sequence cannot be saved, you will see a short explanation. Update the steps or messaging to make it more distinct, then try again.
These checks help keep your templates useful and prevent empty or near-identical copies from being created.
We have also moved the Save as template button to the top bar alongside the other sequence actions, making it easier to find.
