## Summary
Minor cleanup flagged by newer gcc:
- Removed unused variables
- Removed unimplemented function declaration
- `static` -> `inline` to avoid per-TU duplication

## Summary
I love the new screenshot feature but I can tell that soon I'm gonna
have a folder full of screenshots and not know what's what. It would be
great if the folder could self organize.
When a screenshot is taken while reading, the filename would now include
the book title, chapter (EPUB), page number, and progress percentage.
Example: My-Great-Book_ch3_p5_42pct_12345.bmp
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
* **What changes are included?**
## Additional Context
* Non-reader screens keep the existing screenshot-<millis>.bmp naming.

I reviewed all the changes but I don't have any experience with this
project so this is my best guess
## Summary
This fixes navigating back from the BMP Viewer to the FileBrowser which
was broken when moving to the new ActivityManager
This is fixed by making FileBrowserActivity able to take a full file
path on enter and splitting the basePath and fileName from it and
navigating to the correct place.
fixes:

duplicates:
https://github.com/crosspoint-reader/crosspoint-reader/pull/910 to some
extend but mine has the file cursor at the correct file instead of the
first one in the folder
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).

## Summary
**What is the goal of this PR?**
This change avoids the pattern of creating a `std::string` using
`.substr` in order to compare against a file extension literal.
```c++
std::string path;
if (path.length() >= 4 && path.substr(path.length() - 4) == ".ext")
```
The `checkFileExtension` utility has moved from StringUtils to
FsHelpers, to be available to code in lib/. The signature now accepts a
`std::string_view` instead of `std::string`, which makes the single
implementation reusable for Arduino `String`.
Added utility functions for commonly repeated extensions.
These changes **save about 2 KB of flash (5,999,427 to 5,997,343)**.
