* Add support for configuring and using multiple OPDS servers, replacing
the previous single-server limitation. Closes
https://github.com/crosspoint-reader/crosspoint-reader/issues/1178
* New OpdsServerStore singleton (modeled after WifiCredentialStore) that
persists up to 8 OPDS servers to /.crosspoint/opds.json with MAC-based
password obfuscation.
* One-time migration from legacy single-server fields in
CrossPointSettings to the new store on first boot.
* New OpdsServerListActivity for the device UI — works in two modes: a
settings list (add/edit/delete servers) and a picker (select which
server to browse). When only one server is configured, the picker is
skipped automatically.
* Renamed CalibreSettingsActivity → OpdsSettingsActivity for clarity. It
now edits individual OpdsServer entries (name, URL, username, password,
delete).
* OpdsBookBrowserActivity now receives an OpdsServer at construction and
uses its credentials for all fetches/downloads, and shows the server
name in the header.
* HttpDownloader::fetchUrl and downloadToFile accept optional per-call
username/password parameters instead of reading from global settings.
* REST API endpoints on CrossPointWebServer: GET /api/opds, POST
/api/opds, POST /api/opds/delete — passwords are never exposed over the
API (only a hasPassword flag), and omitting the password field on update
preserves the existing one.
* Web UI (SettingsPage.html) with dynamic OPDS server management cards —
add, edit, save, and delete servers from the browser.

* The OpdsServerStore JSON format and obfuscation scheme are identical
to WifiCredentialStore, so the same JsonSettingsIO infrastructure
handles both.
* The web API uses POST /api/opds/delete instead of DELETE /api/opds
because the ESP32 WebServer doesn't support the DELETE method with a
request body.
* Existing single-server configurations are migrated automatically — no
user action required. After migration the legacy CrossPointSettings
fields are cleared so it only runs once.
* The HttpDownloader changes are backward-compatible: the credential
parameters default to empty strings, so existing callers are unaffected.

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Implement automatic dark theme on server files.
Instead of a big change proposed in
https://github.com/crosspoint-reader/crosspoint-reader/pull/837, this PR
introduces a simple implementation of light/dark themes.
* **What changes are included?**
- Choose `#6e9a82` as accent color (taken from
)
- Implement a very basic media query for dark themes (`@media
(prefers-color-scheme: dark)`)
- Update style using CSS variables
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
We can think of it as a incremental enhancement, this is the first phase
of a series of PRs (hopefully).
Next steps/Phases:
1. Light/Dark themes (this PR)
2. Load external CSS file to avoid duplication
3. HTML enhancement (for example, use dialog element instead of divs)
4. Use SVG instead of emojis
5. Use Vite + Typescript to improve DX and have better minification

## Summary
This is an updated version of @itsthisjustin's #346 that builds on
current master and also deduplicates the settings list so we don't have
two copies of the settings. In the Web UI, it should organize the
settings a little closer to what you see on device.
## Additional Context
I tested this live on device and it seems to play nicely for me. It's
re-based on master since master's settings stuff has moved somewhat
since the original PR and addresses the sole review comment #346 - it
also means that I don't need to manually key in the URL for my OPDS
server. :)

### AI Usage
My changes were implemented with Claude Opus 4.5 and Claude Code 2.1.25.
I don't know if @itsthisjustin's original work used AI assistance.
