feat(history): add modular watch history providers

[voidxela]

Summary

Add a provider-neutral watch-history subsystem so new AIOStreams Kodi users receive watched state, resume points, and Next Up without configuring a Trakt account. Existing authorized Trakt users retain their behavior through a legacy compatibility provider, while Trakt watchlists remain independent.

Changes

• Add history models, provider contract, manager fallback behavior, Local History storage, and a legacy Trakt adapter.
• Persist local history and episode catalogs in versioned profile-local SQLite tables shared with recent searches.
• Route playback monitoring, resume application, watched UI state, Next Up, and context actions through generic history actions.
• Add History & Progress settings, one-time legacy-provider selection, an explicit cached-Trakt import action, tests, and documentation.

Verification

• python3 -m unittest discover -s tests -v — 70 tests passed.
• git diff --check — passed before commit.

Notes

• Manual Kodi validation remains recommended for playback callbacks, resume behavior, and legacy-token upgrade flows.
