feat(cli): sync function interval in init, pull and push

[ChiragAgg5k]

Functions can now run on an interval (minutes) instead of a cron schedule (appwrite/appwrite#14231). This teaches the CLI about it:

• appwrite init function writes "interval": 0 next to "schedule".
• appwrite pull functions keeps interval from the server.
• appwrite push functions sends interval and shows it in the change table.

Push only sends keys present in the config, and the server keeps the stored interval when interval is omitted (appwrite/appwrite#14307). So a config written before this change no longer clears an interval set in the Console.

Also bumps the CLI's Go SDK to v7.9.0, the release that adds interval.

Test Plan

• TestFunctionWriteBodySendsIntervalOnlyWhenConfigured: a config without interval sends none, and a configured one is sent.
• On the generated example CLI: go mod tidy, gofmt, go build, go vet and go test -race ./... all pass.

Related: appwrite/appwrite#14170

Also bumps the validation Go toolchain from 1.26.6 to 1.26.9. govulncheck was failing the go (server) check on main (GO-2026-6617, an HPACK race in net/http, fixed in go1.26.9).
