[FEATURE] Add spell-checking to pre-commit hooks

[mr-raj12]

The problem

Currently, there is no automated way to catch spelling mistakes in documentation files (*.md), code comments, docstrings, and UI widget names. Typos reduce readability, look unprofessional, and cause confusion—especially for non-native English speakers.

Recent example: Issue #2371 identified several spelling errors (incase, everytime, wont, posess, seperator) that could have been caught automatically before committing.

Requested Solution

Add codespell to the existing pre-commit configuration (.pre-commit-config.yaml) to catch spelling errors locally before commits are made.

Example pre-commit hook:

- repo: https://github.com/codespell-project/codespell
  rev: v2.2.6
  hooks:
      - id: codespell
        args: [--ignore-words-list, "borg,vorta,deduplicated,uncompress"]
        exclude: "^(.*\\.ts|.*\\.lock)$"

Benefits:

1. Catches typos before code is pushed
2. No CI changes needed—uses existing pre-commit infrastructure
3. Runs automatically for contributors who use pre-commit install
4. Lightweight and fast

Alternatives

1. CI-based spell-checking — Adds CI complexity and slower feedback loop
2. Manual review — Current approach; error-prone and time-consuming
3. Use typos instead of codespell — Lower false-positive rate but less mature pre-commit support

Additional context

• Vorta already uses pre-commit hooks (ruff, trailing whitespace, etc.)
• A custom ignore-words list can exclude project-specific terms
• Translation files (.ts) should be excluded to avoid false positives on non-English strings
