fix(deploy): ship data/ so Docker images keep their baked plugin previews (#7028)

`deploy/Dockerfile` copies skills, design-systems, craft, prompt-templates,
assets and plugins/_official, but not data/ — so
`data/plugin-previews/manifest.json`, which CI commits precisely so deployments
can find the bakes, is absent at runtime. `resolvePluginPreviewsDir()` defaults
to <projectRoot>/data/plugin-previews, `loadManifest()` returns {},
`applyBakedPreviews()` returns the records untouched, and
`inferPluginPreview(record, { preferBaked: true })` falls through to the live
iframe for every plugin.

Measured on 0.19.2 with 461 registered plugins: the checked-in manifest has 176
entries and 0 records carried od.bakedPreview. With data/ present the same
daemon reports 176 — deck 79, prototype 79, video 10, scenario 4, image 1,
audio 1, template 2. The packaged app reaches the manifest through its own
packaging path, so only Docker/self-hosted deployments are affected.

Also warn once per path when the manifest is absent. `loadManifest()` already
carries the reasoning for the malformed case — «would otherwise silently
disable every baked preview with no trace; surface it so it's diagnosable» —
but the absent branch returned {} with no message, which is the same failure
with the same lack of trace.

Fixes #7018
