feat: Allow directly creating dashboard template from table

[I-Dont-Remember]

Allow users to create new dashboard template direct from table, not just the New modal, which can take more clicks.

This is a UX suggestion - since it was so small I didn't raise an Issue first, so feel free to close if it doesn't fit with ya'lls product goals.

Problem

As a user of Posthog, I was confused when I wasn't able to interact and create a new Dashboard directly from a template in the list - I had to first decide which one I liked, and then open up the New Dashboard modal, search for the one I wanted, and then click it. There was more friction than I had hoped.

My ideal flow as a user would be:

• Read through all the entries in table
• Decide on one and click the row name to create it

Changes

Updated the table of Dashboard template options so that the name is a clickable button (which creates a new dashboard with that template, same as choosing from modal) rather than just text string.

Does this work well for both Cloud and self-hosted?

How did you test this code?

• Ran the app locally (see screenshot). Created a new dashboard in the local environment by using the new button.
• Tried to run all the relevant frontend tests - though it feels like Developing Locally doc might be out of date, because pnpm test:unit doesn't seem to be a valid command - or my setup is wonky. Went with what I hoped was close to same level of coverage:

> pnpm --filter frontend test
....
Test Suites: 157 passed, 157 total
Tests:       3 skipped, 1670 passed, 1673 total
Snapshots:   76 passed, 76 total
Time:        354.551 s
Ran all test suites matching /(frontend\/|products\/|common\/)/i.
