fix: word count calculation

This fixed various issues related to calculating streaks, etc. Now we
appropriately handle time as it was, vs as it is relative to an offset.

-This is BookManager! Will probably be renamed at some point. This repository contains:
+AnthoLume is a Progressive Web App (PWA) that manages your EPUB documents, provides an EPUB reader, and tracks your reading activity! It also has a [KOReader KOSync](https://github.com/koreader/koreader-sync-server) compatible API, and a [KOReader](https://github.com/koreader/koreader) Plugin used to sync activity from your Kindle. Some additional features include:
 
-- [KOReader KOSync](https://github.com/koreader/koreader-sync-server) Compatible API
+- OPDS API Endpoint
-- KOReader Plugin (See `client` subfolder)
+- Local / Offline Reader (via ServiceWorker)
-- WebApp
+- Metadata Scraping (Thanks [OpenLibrary](https://openlibrary.org/) & [Google Books API](https://developers.google.com/books/docs/v1/getting_started))
+- Words / Minute (WPM) Tracking & Leaderboard (Amongst Server Users)
 
-In additional to the compatible KOSync API's, we add:
+While some features require JavaScript (Service Worker & EPUB Reader), we make an effort to limit JavaScript usage. Outside of the two aforementioned features, no JavaScript is used.
 
-- Additional APIs to automatically upload reading statistics
+## Server
-- Automatically upload documents to the server (can download in the "Documents" view)
-- Book metadata scraping (Thanks [OpenLibrary](https://openlibrary.org/) & [Google Books API](https://developers.google.com/books/docs/v1/getting_started))
-- No JavaScript! All information is generated server side.
 
-# Server
+Docker Image: `docker pull gitea.va.reichard.io/evan/antholume:latest`
 
-Docker Image: `docker pull gitea.va.reichard.io/evan/bookmanager:latest`
+### Local / Offline Reader
 
-## KOSync API
+The Local / Offline reader allows you to use any AnthoLume server as a standalone offline accessible reading app! Some features:
+
+- Add local EPUB documents
+- Read both local and any cached server documents
+- Maintains progress for all types of documents (server / local)
+- Uploads any progress or activity for cached server documents once the internet is accessible
+
+### KOSync API
 
 The KOSync compatible API endpoint is located at: `http(s)://<SERVER>/api/ko`
 
-## Quick Start
+### OPDS API
+
+The OPDS API endpoint is located at: `http(s)://<SERVER>/api/opds`
+
+### Quick Start
+
+**NOTE**: If you're accessing your instance over HTTP (not HTTPS), you must set `COOKIE_SECURE=false`, otherwise you will not be able to login.
 
 ```bash
 # Make Data Directory
-mkdir -p bookmanager_data
+mkdir -p antholume_data
 
 # Run Server
 docker run \
     -p 8585:8585 \
+    -e COOKIE_SECURE=false \
     -e REGISTRATION_ENABLED=true \
-    -v ./bookmanager_data:/config \
+    -v ./antholume_data:/config \
-    -v ./bookmanager_data:/data \
+    -v ./antholume_data:/data \
-    gitea.va.reichard.io/evan/bookmanager:latest
+    gitea.va.reichard.io/evan/antholume:latest
 ```
 
 The service is now accessible at: `http://localhost:8585`. I recommend registering an account and then disabling registration unless you expect more users.

-# Client (KOReader Plugin)
+## Security
 
-See documentation in the `client` subfolder: [SyncNinja](https://gitea.va.reichard.io/evan/BookManager/src/branch/master/client/)
+### Authentication
 
-# Development
+- _Web App / PWA_ - Session based token (7 day expiry, refresh after 6 days)
+- _KOSync & SyncNinja API_ - Header based - `X-Auth-User` & `X-Auth-Key` (KOSync compatibility)
+- _OPDS API_ - Basic authentication (KOReader OPDS compatibility)
 
-SQLC Generation (v1.21.0):
+### Notes
+
+- Credentials are the same amongst all endpoints
+- The native KOSync plugin sends an MD5 hash of the password. Due to that:
+- We store an Argon2 hash _and_ per-password salt of the MD5 hashed original password

-# Building
+## Building
 
 The `Dockerfile` and `Makefile` contain the build information:
 
 ```bash
+# Build Local (Linux & Darwin - arm64 & amd64)
+make build_local
+
 # Build Local Docker Image
 make docker_build_local
 
-# Push Latest
+# Build Docker & Push Latest or Dev (Linux - arm64 & amd64)
 make docker_build_release_latest
-```
+make docker_build_release_dev
 
-If manually building, you must enable CGO:
+# Generate Tailwind CSS
+make build_tailwind
 
-```bash
+# Clean Local Build
-# Download Dependencies
+make clean
-go mod download
 
-# Compile (Binary `./bookmanager`)
+# Tests (Unit & Integration - Google Books API)
-CGO_ENABLED=1 CGO_CFLAGS="-D_LARGEFILE64_SOURCE" go build -o /bookmanager
+make tests_unit
+make tests_integration

+# DB Migrations
+
+```bash
+goose create migration_name

+
+## Note
+
+Since we update both the `schema.sql`, as well as the migration files, when we create a new DB it will inherently be up-to-date. We don't want to run the migrations if it's already up-to-date. Instead each migration checks if we have a new DB (via a value passed into the context), and if we do we simply return.
