feat: TransactionComposer & AppManager implementation; various ongoing refactoring efforts

[aorumbayev]

Proposed Changes

• Add AppManager class with methods for compiling TEAL, managing app state, and handling template variables. Reusing existing methods from deploy.py in legacy.
• Update TransactionComposer to use AppManager
• Move Account model back from legacy folder into a dedicated account namespace under models folder.
• Add new models for ABI values and application constants
• Improve type annotations and remove unnecessary type ignores
• Add initial tests for AppManager template substitution and comment stripping
• Update mypy configuration to globally exclude untyped calls in algosdk -> removing ~50 individual mypy type ignore for algosdk

TODO

• Implement remaining feature parity on beta composer
• Add composer tests

@robdmoore @neilcampbell , please ignore the dummy stubs for AssetComposer and AlgorandClientTransaction(Sender|Creator), had to fill those with initial data to ensure CI is passing, the main scope of the pr is still AppManager and TransactionComposer. Should be ready for initial review, will merge Monday and continue with remaining abstractions (next 2 prs are going to be around AlgorandClientTransaction(Sender|Creator) and AppClient)
