BlotzTask-ADHD Time Manager

## New Features * Improved the monthly review calendar for a better user experience and AI-generated responses, including clearer prompts, privacy-safe sharing, and accurate month-end behavior. * Your reviews just got more frequent — Blotz now writes you a weekly letter reflecting on your week, alongside your monthly one. * Users can now see task filters in a clearer fixed order: **To Do, Overdue, Completed, and All**. * Fixed overdue logic: removed overdue selection from the monthly calendar and weekly availability to provide a cleaner interface without interruptions from overdue tasks. * Retained the voice input page as the default option. Added a keyboard toggle button; tapping it automatically opens the keyboard, while tapping the microphone button switches back to voice input. * Added a badge wall preview to the Settings page, displaying earned badges. Tapping a badge opens the new Badge Wall page, where users can view all earned badges. ## Bug Fixes * Fixed an issue where AI task generation displayed raw numbers instead of natural duration phrases such as "within a month" in task descriptions. * Users now stay signed in without being randomly logged out. Authentication tokens refresh silently in the background, and sign-in is only required when a session genuinely expires. * Fixed an issue where adding new subtasks without changing the title would incorrectly display an error. * Fixed an Android issue where task swipe actions for Pomodoro mode and Focus could not be tapped. ## Beta Features * Added recurring task support across backend APIs, calendar/deadline queries, and mobile task flows. Users can now create recurring tasks and manage individual or future occurrences. * The **Repeat** field is now marked as **Beta** while recurring tasks continue to roll out. * Users can now share an earned badge as an image directly from the achievement popup.
