fix: changing image filename exported to anki to use only lowercase

[marcomachado]

Closes #701

This PR changes the Anki export image filename prefix from uppercase LUTE_TERM_ to lowercase lute_term_ to ensure compatibility with newer versions of Anki.

• Updated handle_image in lute/ankiexport/field_mapping.py to generate the image prefix in lowercase (lute_term_). Both the HTML reference and the stored filename parameter will now be sent to Anki in lowercase.
• Updated unit and integration tests to verify the lowercase prefix and swapped payload execution order.

Does it still work with older versions of Anki? Ie if I use this new code but I have an older version of Anki, will Anki still show the image?

Yes! I think so, but, in fact, I didn't test it

Anki now defines a default way to saved images filenames instead of rely it to other applications (like Lute which decided to use upper case)

But old cards are already exported and configured using upper case, both in card (img src) and image file in filesystem

If a user uses an older version of anki and creates a new card: Anki will rely of Lute to define filename for images and a card will be generated using lowercase

[marcomachado]

Tests:

For new files:

• ideal scenario: LUTE (branch version) + Anki (current version) = LUTE will create cards already with lowercase; anki will save with lowercase (default)

Alternatives scenarios:

• [BUG] LUTE (current version) + Anki (current version) = bug (LUTE will use uppercase; Anki now uses lowercase)
• [OK] LUTE (current version) + Anki (old version) = Anki will rely on Lute to define filename, so files will be saved using uppercase
• [OK] LUTE (branch version) + Anki (old version) = Anki will rely on Lute to define filename, so files will be saved using uppercase

For old files: Anki don't change already saved cards and files
