fix: support copying internal images with size parameters

[footmanFF]

Fixed an issue where internal images with size parameters (e.g., ![[image.png|100]]) were failing to copy in Rich Text mode.

Changes:

• Correctly parse image filename by ignoring parameters when looking up files in the vault.
• Applied width/height parameters to the generated tag style in Rich Text mode, preserving the visual layout.
• Fixed copyAsMarkdown to also handle image links with parameters correctly.
