refactor(init): split init flows into separate functions

[rexxars]

Note

This is part 2 of a larger init refactor. See #748 for part 1.

Makes it easier to reason about and make changes to each individual init flow.

scaffoldTemplate.ts:61-70 — Studio-specific fields required in shared interface

ScaffoldOptions declares projectId: string, datasetName: string, and displayName: string as required, even though they're meaningless for the app flow. This forces initApp to pass empty strings with a comment to explain why. Consider making them optional (projectId?: string, etc.) and having bootstrapTemplate handle undefined (it already falls back via displayName || defaults.projectName).

Fix this →

initNextJs.ts:248-350 — writeOrOverwrite / writeSourceFiles are private to this file but duplicate the pattern from initAction.ts

These helpers were moved verbatim from the old monolithic file — no issue there — but writeOrOverwrite silently swallows mkdir errors (catch { debug(...) }) without any fallback. If directory creation fails and the file write then fails, the error from writeFile will be thrown with no context about the directory creation failure. Same behavior as before, but worth noting since it's now more visible in isolation.

---

No other behavioral differences found. The refactoring is functionally equivalent to the original code.
