[GPS] Add custom compass to GPSMapView

[GCyganek]

Explanation of Change

Extracted the custom compass into a shared Compass component and added it to GPSMapView, replacing the native Mapbox compass. Also renamed useAnimatedTrailingDirectionCoordinate to useAnimatedLeadingDirectionCoordinate for clarity, fixed typo and renamed interpolateCoordinate() function according to feedback from #91418.

PR Author Checklist

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section
  • I added steps for the expected offline behavior in the Offline steps section
  • I added steps for Staging and/or Production testing in the QA steps section
  • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
  • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
• I included screenshots or videos for tests on all platforms
• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (see Reviewing the code)
  • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
  • I verified that comments were added to code that is not self explanatory
  • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
  • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
• If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
• I followed the guidelines as stated in the Review Guidelines
• I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• If any new file was added I verified that:
  • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
• If a new CSS style is added I verified that:
  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
• If new assets were added or existing ones were modified, I verified that:
  • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
  • The assets load correctly across all supported platforms.
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
• I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
• If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

I'll review it since it's my regression

Not really your regression, we just merged two PRs at the same time where one was adding GPSMapView and the other was adding custom compass to the default MapView which was the only variant at the time and I didn't realise that it would end up like this 😅

🤖 No help site changes required.

I reviewed the changes in this PR and they don't warrant any updates to the help site articles under docs/articles.

Why: This is a purely internal/cosmetic UI refactor:

• Extracts the existing custom compass into a shared Compass component and uses it on GPSMapView, replacing the native Mapbox compass so the GPS map matches the Map tab's compass icon.
• Renames an internal hook (useAnimatedTrailingDirectionCoordinate → useAnimatedLeadingDirectionCoordinate) and an internal helper function for clarity.

There's no new feature, no change to a documented user flow, and no new setting/label/button that the help site describes. The help site documents how to create distance expenses (e.g. Distance-Expenses.md), not the map's compass control — and a search of docs/ turns up no article referencing the compass. Swapping one compass icon for a visually consistent one doesn't change any documented behavior, so no HelpDot PR is needed.

If the team later decides the distance/map UI should be documented in more detail, that would be a separate docs effort rather than something driven by this refactor.

@GCyganek — since no documentable behavior changed, I did not create a help site PR, so there's nothing to review or mark Ready for review. If you believe a docs update is warranted here, let me know what behavior should be documented and I'll draft one.
