Fixes the three revenue issues reported in the assignment:

• Incorrect March totals: Filter reservations by the selected month using each property’s local time zone, including daylight-saving changes. Added a reporting-month selector and corrected the database connection configuration.
• Cross-client revenue leakage: Include tenant, property, and reporting period in cache keys. Ignore legacy shared entries, verify cached ownership, and remove hardcoded revenue fallbacks.
• Cents discrepancies: Sum amounts at full decimal precision, round the final total once using ROUND_HALF_UP, and return a decimal string for display without floating-point conversion.
  Also installs SQLAlchemy’s asyncio dependencies to resolve the missing greenlet error.

One more thing:
I also added __pycache__ to .gitignore because the app hot-reloads from the host's repo and generate these files which pollutes git's changes.

Bug: Partial or invalid text in <input type="month"> fallback inputs triggers API requests with invalid month/year parameters, resulting in 422 errors.
_{Severity: LOW}

Suggested Fix

Validate that the input matches the expected YYYY-MM format (e.g. using a regular expression /^\d{4}-\d{2}$/) before updating period and triggering queries.

Potential issue: On browsers lacking native `<input type="month">` support, the control
defaults to a plain text field where `validity.valid` evaluates to true for non-empty
text. Typing partial or invalid input like '2024-' or 'abc' updates `period`, resulting
in invalid `month` and `year` values such as 0 or `NaN`. These values trigger API
requests on each keystroke that fail with 422 errors and cause the UI to display 'Failed
to load revenue data'.

Here's my loom video:

When I recorded the video it was more than 18 minutes, so I cut some parts, sorry if that makes the video a little inconvenient.
