Refactor report.ts: clarify variable names and extract magic numbers

[Copilot]

Applied variable naming improvements and extracted magic numbers in src/lib/data/report.ts for better code clarity.

Changes

• Renamed ambiguous loop variables: idx → eventIndex, t → bucketTime
• Renamed abbreviated variables: evts → userEvents, l → log
• Extracted grid layout constant: 6 → ROWS_PER_COLUMN at module level

Example

// Before
let idx = 0;
for (let t = bucketStart; t <= maxTime; t += bucketSize) {
  while (idx < events.length && events[idx].time < t + bucketSize) {
    // ...
  }
}

// After
let eventIndex = 0;
for (let bucketTime = bucketStart; bucketTime <= maxTime; bucketTime += bucketSize) {
  while (eventIndex < events.length && events[eventIndex].time < bucketTime + bucketSize) {
    // ...
  }
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint.prisma.io
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/OverHours/OverHours/node_modules/prisma/build/child {"product":"prisma","version":"6.19.2","cli_install_type":"local","information":"","local_timestamp":"2026-01-30T17:22:18Z","project_hash":"da61a9b6","cli_path":"/home/REDACTED/work/OverHours/OverHours/node_modules/.bin/prisma","cli_path_hash":"c1b7c8a6","e (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
