fix: show correct max file size in CSV import dialog

[premtsd-code]

Summary

• The file picker's local file upload showed a hardcoded "Max file size: 10MB" which was incorrect
• Now dynamically reads the plan-based fileSize limit on cloud and displays it using humanFileSize() (e.g. 50MB for Starter, 5GB for Pro/Scale)
• Fix inconsistent dropzone text across all file upload components — standardized to "Drag and drop a file here or click to upload" (9 files)

Test plan

• Open CSV import dialog on a Pro plan — should show "Max file size: 5GB"
• Open CSV import dialog on a Starter plan — should show "Max file size: 50MB"
• Verify dropzone text reads "Drag and drop a file here or click to upload" in: CSV import, storage file create, env variable import (project + function), site deploy, function deploy, domain record import

Greptile Summary

This PR replaces the hardcoded "Max file size: 10MB" label in filePicker.svelte's local-file upload dropzone with a dynamically computed value derived from the current billing plan's fileSize field (converted from MB to bytes via sizeToBytes, then formatted with humanFileSize). The approach is consistent with the same pattern already used in updateMaxFileSize.svelte. The remaining eight files receive a minor copy fix ("files" → "a file") in drag-and-drop labels.

• planMaxSize correctly handles the cloud/self-hosted split: on self-hosted (isCloud === false) the caption is suppressed entirely; on cloud it reads $currentPlan['fileSize'] (a number in MB) and converts it with base-1000 arithmetic, matching existing billing helpers.
• sizeToBytes(value, 'MB', 1000) conversion is correct and consistent with the updateMaxFileSize.svelte pattern (service * 1000 * 1000).
• The caption is now hidden on self-hosted — this is a behaviour change from the old hardcoded 10 MB, and may be worth explicitly documenting as intentional since self-hosted has no plan-based limits.

Confidence Score: 5/5

Safe to merge — the core logic change is correct and consistent with existing billing helpers; the only open item is a minor UX consideration on self-hosted.

All remaining findings are P2. The dynamic size computation matches the established pattern in updateMaxFileSize.svelte. No data loss, security, or runtime-error risk.

src/lib/components/filePicker.svelte — only file with logic changes; all others are copy-only edits.

Missing space between value and unit

readableMaxSize.value + readableMaxSize.unit produces "50MB" or "5GB" with no space. The existing usage in updateMaxFileSize.svelte does the same thing (line 51: {Math.floor(parseInt(size.value))}{size.unit}), so this is consistent with the codebase convention. That said, the humanFileSize helper returns a space-separated pair from prettyBytes precisely to allow callers to format them separately — displaying "5 GB" is more readable and closer to the format prettyBytes produces internally. Consider adding a space:

Suggested change

	>Max file size: {readableMaxSize.value +
	readableMaxSize.unit}</Typography.Caption>
	>Max file size: {readableMaxSize.value + ' ' +
	readableMaxSize.unit}</Typography.Caption>
