First off, kudos for providing the details, that really helps! The root of your problem is that your suggest field has stored="false". DocumentDictionaryFactory reads through all the docs in your corpus, extracts the stored data and puts it in the FST. Since you don't have any stored data your FST is...er...minimal.
I'd also add <str name="storeDir">suggester_fuzzy_dir</str> to the searchComponent. You'll find the FST on disk in that directory where it can be read next time Solr starts up. It is also helpful for figuring out whether there are suggestions to be had. And a minor nit, you probably don't want to specify suggest.dictionary in your query, that's already specified in your config. And it looks like you're alive to the fact that with that setup capitalization matters as does the fact that these suggestions be matched from the beginning of the field...
