Auto-learn from corrections + bulk dictionary import

Hi Vowen team,

First off, I really like your project, it's really useful.

I wanted to share a couple of ideas that would make it even more powerful:

1. Auto-learn from manual corrections

When a word gets transcribed incorrectly and I fix it by hand in the text, it would be great if the app noticed that and silently added the correction to my custom dictionary in the background. So the next time I say the same thing, it already knows what I mean - no extra steps.

For example, I often say "DeepL" (the translation tool), and Vowen transcribes it as something like "dipl". If it learned from that first correction, I'd never have to fix it again.

2. Bulk import words via .txt or .csv file

Right now, adding technical or niche vocabulary one word at a time can be pretty tedious. It would be really handy to be able to upload a plain text or CSV file with a list of words to add to the dictionary all at once.

This would be especially useful for people who work in specific fields - for example, developers who regularly say things like MySQL, PHP, Supabase, or prompt engineering terms, or really anyone working in a niche where standard speech recognition tends to struggle. Being able to prepare a word list in advance and import it in one shot would save a lot of time.

Thanks for considering it, and keep up the great work!
