feat(sltt-app): add contextbridge api for storing videos to local disk outside of browser

What issue(s) is this trying to resolve?

feat(sltt-app): add contextBridge api for storing videos to local disk (outside of browser) #6

How does it all work?

added ipcMain.handle() for ipcRenderer messages storyVideoBlob and tryRetrieveVideoBlob
blobs are actually read/written using ArrayBuffers
store (and get) video blobs under %APPDATA%/sltt-app/persistentStorage/{projectName}/{_id}/{blob-num} (see app.getPath docs)
storeVideoBlob will return debug information about video file paths and buffer length.
tryRetrieveVideoBlob will return the arrayBuffer for the file if found, otherwise it returns null for file not found error, otherwise throws an error. (try in tryRetrieveVideoBlob interface means return null if not found)
Both interfaces try to throw type errors found in the args

What particularly has changed?

update electron-vite-config.ts so storage/index.ts gets compiled and included in build in out/main/storage.js
update version to 205104.0.22-alpha1 (2.51.4)
import ./storage.js
add storage/index.ts to define ipcMain handlers for storeVideoBlob and tryRetrieveVideoBlob messages

Steps for testing
