Fix make reindex targets and reindex Obsidian in the vector store CLI

`make reindex` and `make reindex-obsidian` built a `python -c` string with
backslash continuations, which kept the tab indentation inside the code, so
Python failed with IndentationError. The targets now call the existing
`scripts.manage_vectorstore` CLI. Its `reindex` wiped everything but only
re-indexed Paperless, dropping Obsidian notes; it now indexes both, and a new
`reindex-obsidian` command re-embeds only the vault.
