feat(sltt-app): add proxy server for local team storage

[ericpyle]

What issue(s) is this trying to resolve?

• feat(sltt-app): add proxy server for local team storage feat(sltt-app): add proxy server for local team storage #49
• fix(sltt-app) await readJsonCatchMissing to avoid Unexpected end of JSON input errors

How does it all work?

• add await to readJsonCatchMissing calls to avoid Unexpected end of JSON input errors race-conditions
• replace storage/index.ts ipcMain handlers with express storage/server.ts app
• enforce localhost requests for most hostFolder and connection api requests
• all other requests must include a x-sltt-app-storage-server-id header which must match the host's serverId, otherwise the server will respond with 403 Forbidden.
• provide hostFolder api to enable allowHosting and to establish a directory for hosting
  • automatically ensure that hostFolder ends with sltt-app/lan and provides diskUsage and error feedback
• setup a udp client and regularly broadcast host state to peers, and allow peers to respond to each host with their own PeerInfo
• host should prune peers that have not inherited the latest hostUpdatedAt
• regularly prune obsolete hosts, if my own peer information in those hosts was updatedAt beyond expiration threshold
• probeConnections api uses the serverState.hosts in order to provide connection info for those hosts.
  • for now, disable samba support (but keep most of its code)
  • updateWifiConnections() is called to provide wifi networkName information
  • username information is now used to set serverState.myUsername which is used to communicate which user is associated with each host computer
  • instead of urls, the connectionInfo in the response includes serverId for each host.
  • The serverId is required for subsequent CONNECTIONS_API_CONNECT args which is used to establish serverState.proxyServerId and proxyUrl
  • proxyServerId is used to provide hosts with isClient feedback to help determine how many computers are clients of the host server
  • if disk usage falls below MIN_DISK_SPACE_MB, then accessible will be false for that connection.

What particularly has changed?

• move storage server from js to ts compilation
• refactor to pass configFilePath into startStorageServer
• update StoreBlobArgs to take blob (for multer multiUpload api)
• revise connections api
  • add startUdp route
  • add username to probeConnections, remove urls
  • add connectionInfo to probeConnections response
• change storeVcr api
  • add batchMaxTime?: number, batchMaxSize?: number arguments to allow client greater control of batch process
• fix typescript errors
• enforce localhost requests for the following routes:
  • HOST_FOLDER_API_LOAD_HOST_FOLDER
  • HOST_FOLDER_API_SAVE_HOST_FOLDER
  • HOST_FOLDER_API_CAN_WRITE_TO_FOLDER
  • HOST_FOLDER_API_GET_ALLOW_HOSTING
  • HOST_FOLDER_API_SET_ALLOW_HOSTING
  • CONNECTIONS_API_START_UDP
  • CONNECTIONS_API_PROBE
  • CONNECTIONS_API_CONNECT
• remove storage rollupOption from electron.vite.config.ts in favor of adding "storage/*" to tsconfig.node.json
• add axios, body-parser, diskusage, multer, and node-wifi packages
