Treat empty or whitespace-only dataDirOverride values as unset so
bootstrapEnv keeps using the normal DATA_DIR and .env lookup path.
Adds a focused regression test for the whitespace override case.
Propagate database inspection failures instead of treating them as
missing encrypted credentials.
This keeps startup from generating a fresh encryption key when an
existing database cannot be inspected and adds a regression test for
that path.
Align the app bootstrap paths with the documented CLI env lookup.
The CLI wrapper already loads DATA_DIR/.env, ~/.omniroute/.env, or ./.env,
but run-next, run-standalone, and Electron were bypassing that behavior.
On machines with encrypted credentials, that could generate a fresh
STORAGE_ENCRYPTION_KEY in server.env and make existing tokens unreadable.
This change:
- uses the same preferred .env lookup in bootstrapEnv and Electron
- keeps Electron secrets rooted in DATA_DIR and passes DATA_DIR to the child
- refuses to mint a new encryption key over an existing encrypted database
- adds a focused regression test for env precedence and key safety
