feat(file-browser): make entire file card clickable in list view

Improve the user experience in the file browser list view by allowing users to click anywhere on a file card to open it, rather than just the specific link. - Add a click event listener to the file browser to handle navigation when clicking a card in list view. - Ensure interactive elements (like buttons or inputs) inside the card do not trigger the card-wide click. - Add `cursor: pointer` to list view file cards to indicate they are clickable. - Update retro theme CSS to style the entire card on hover and focus.
feat(ui): limit visible reactions and overhaul retro theme

+## Emoji reaction packs
+
+File reactions use emoji packs from the runtime data directory, not from the application code. By
+default that means `./data/emoji`; if you change `WARPBOX_DATA_DIR`, use
+`$WARPBOX_DATA_DIR/emoji` instead.
+
+Each folder under `./data/emoji` becomes one emoji tab in the reaction picker. Put image files
+directly inside the pack folder:

+```text

+## Large Uploads
+
+Multi-GB uploads must not use whole-body read/write deadlines. Keep these
+Warpbox values for production unless you intentionally want a hard wall-clock
+upload limit:

+`WARPBOX_READ_HEADER_TIMEOUT` protects request headers. `WARPBOX_READ_TIMEOUT`
+and `WARPBOX_WRITE_TIMEOUT` cover the whole upload/response lifetime in Go, so
+small values can cause browser errors such as `NS_ERROR_NET_INTERRUPT` during
+large transfers. Upload size, daily, storage, and box limits still enforce abuse
+controls independently of these timeout values.

Author	SHA1	Message	Date
Daniel Legt	d3b6a86753	feat(file-browser): make entire file card clickable in list view All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m45s Details Improve the user experience in the file browser list view by allowing users to click anywhere on a file card to open it, rather than just the specific link. - Add a click event listener to the file browser to handle navigation when clicking a card in list view. - Ensure interactive elements (like buttons or inputs) inside the card do not trigger the card-wide click. - Add `cursor: pointer` to list view file cards to indicate they are clickable. - Update retro theme CSS to style the entire card on hover and focus.	2026-06-02 14:45:55 +03:00
Daniel Legt	cf5d8bb50d	feat(ui): limit visible reactions and overhaul retro theme - Limit the number of initially visible reactions per file to 2 and calculate the overflow count on the backend. - Redesign the retro theme CSS to mimic a classic Windows 98 Explorer window, including title bars, toolbars, and sunken panes. - Add local storage persistence for the file browser view preference (list vs. thumbnails).	2026-06-02 14:43:16 +03:00
Daniel Legt	8e3f783780	feat(handlers): add file icons with standard and retro variants Introduce file icon support to the file browser. Icons are loaded on startup and mapped based on file name and content type. - Load file icon mappings in the App handler initialization. - Add `HasThumbnail`, `IconURL`, and `IconRetroURL` to the file view. - Update CSS to support displaying file icons alongside thumbnails. - Add retro theme support to swap standard icons with pixelated retro variants when the retro theme is active.	2026-06-02 13:02:51 +03:00
Daniel Legt	6c87187c6d	refactor(api): consolidate health check endpoints to /health All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m44s Details Removes the redundant `/healthz` and `/api/v1/health` endpoints, leaving `/health` as the sole health check endpoint. - Update router to return 404 Not Found for the removed endpoints - Update admin log filtering to only ignore `/health` - Remove health URL from API documentation data - Update tests to verify `/health` returns 200 and others return 404 - Update README documentation to reflect the change	2026-06-02 11:54:38 +03:00
Daniel Legt	f628b489af	feat: add emoji reaction support for files All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m46s Details - Implement `ReactionService` to manage file reactions in the database. - Add `POST /d/{boxID}/f/{fileID}/react` endpoint to handle user reactions. - Add `GET /emoji/{pack}/{file}` endpoint to serve custom emoji assets. - Support loading custom emoji packs dynamically from the data directory. - Update README with instructions on configuring emoji reaction packs.	2026-06-02 11:30:33 +03:00
Daniel Legt	1ab5021667	feat(config): support large uploads with read header timeout All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m40s Details Disable default read and write timeouts (set to 0s) to prevent Go from prematurely closing connections during large multi-GB uploads. Introduce `WARPBOX_READ_HEADER_TIMEOUT` (defaulting to 15s) to protect against slowloris-style attacks while still allowing long-running uploads to complete. Update documentation and example configurations accordingly.	2026-06-01 15:23:28 +03:00
Daniel Legt	c9f865cd85	refactor(admin): use inline pixel heights for overview charts All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m40s Details Refactors the admin overview dashboard charts to use inline pixel heights (up to 150px) instead of CSS variables and percentage-based heights. This provides more robust rendering and layout control. Changes include: - Replacing `Height` with `HeightPx` in chart bar structures. - Rendering inline styles for height and width on charts and status bars. - Adding fallback data attributes (`data-height-px`, `data-chart-value`, etc.) and loading a new fallback script (`25-admin-charts.js`). - Updating and expanding test coverage to assert correct scaling and HTML rendering.	2026-06-01 12:30:59 +03:00
