feat(application): add name, tos and plan selection during application creation

[LorrisSaintGenez]

What

• Extend algolia application create: prompt for an app name, select a plan, and confirm the plan's ToS inline. Adds --plan (free/grow/grow-plus) and --accept-terms (-y).
• Paid plans require a payment method on file. When billing is missing the CLI links to the billing page instead of creating the app (it never collects card details), and recognizes grow/grow-plus even when the API hides them (shows the billing message rather than "invalid plan").
• --accept-terms/-y now skips the ToS prompt in interactive mode too — for create and for application upgrade/downgrade.

Test

Build first

make build

• Any account

./algolia application create # can pick name, region and plan
./algolia application create --region EU --plan bogus --accept-terms # invalid plan error

• Account WITH billing info

./algolia application create --region EU --plan free --accept-terms # free, no prompt
./algolia application create --region EU --plan free --accept-terms # free, no prompt
./algolia application create --region EU --plan grow --accept-terms # billing acct -> created on Grow

• Account WITHOUT billing info

./algolia application create  # only free plan should appear during plan selection
./algolia application create --region EU --plan grow   # no billing -> offers billing page, no app
