fix: improve middleware docs and remove non existing sdk api's

[janb87]

Summary by Sourcery

Refactor documentation by introducing reusable snippets for middleware instructions, standardizing the term "Smart contract portal", and removing potentially destructive delete operations from code examples.

Documentation:

• Create reusable snippets for creating and managing middleware.
• Update documentation guides (EVM, Hedera) and component pages to use the new middleware snippets.
• Standardize terminology by renaming "API Portal" to "Smart contract portal" throughout the documentation.
• Remove potentially unsafe delete command examples for various platform components (networks, storage, smart contract sets, middleware).
• Correct the SDK documentation link in the release notes.
• Improve formatting with consistent line breaks and code block language identifiers.

Hey @janb87 - I've reviewed your changes - here's some feedback:

Overall Comments:

• Ensure the corresponding SDK methods for delete operations (networks, storage, smart contract sets) are removed or marked deprecated in the SDK codebase to match the documentation removal.
• Double-check all documentation files for consistent use of 'Smart contract portal' instead of the older 'API Portal' term.
