Commit Summary

Add daily gameplay cap, cap commands, and DB datetime parsing fix

Optional Extended Description

Implemented a gameplay-only daily credit cap system with configurable limits and reset window through DailyEarnedCreditsCap (Enabled, MaxCreditsPerDay, ResetEveryHours). Added bounded reward behavior to prevent over-cap grants (partial credit grant when reward exceeds remaining cap) while preserving existing behavior for non-gameplay credit sources (admin/manual/API/website) and negative credit adjustments. Introduced player/admin operational commands: css_capstatus for cap progress visibility and css_capreset <player|steamid|target> for targeted cap state reset with database persistence. Added one-time notification logic when a player reaches the daily gameplay cap, including config-driven messaging and localization support. Extended language resources with new cap-related keys (cap_reached, cap_status, cap_disabled, cap_reset_success) and added bg.json for Bulgarian localization coverage. Resolved player load instability by fixing DailyGameplayCreditsWindowStart deserialization/parsing in database load flow, preventing Error parsing column ... - Object failures and retry loops.

PR Title

Add daily gameplay credits cap, cap status/reset commands, and DB datetime parsing fix

PR Description

## Summary
This PR adds a daily cap system for gameplay-earned Store credits, new cap-related commands, and a fix for player loading errors caused by `DailyGameplayCreditsWindowStart` parsing.

## What was added

### 1) Daily Gameplay Credits Cap
- Added configurable daily cap section:
```toml
[DailyEarnedCreditsCap]
Enabled = true
MaxCreditsPerDay = 70
ResetEveryHours = 24

• Cap applies only to positive gameplay-earned credits.
• Manual/admin/API/website credits are not capped.
• Negative credits (penalties) still apply normally.
• Partial reward support:
  • example: if player has 68/70 and earns +5, only +2 is granted.
• Reset window is configurable (ResetEveryHours, default 24h).

2) New Commands

• css_capstatus (player command)
  • Shows current cap progress, remaining credits, and reset time.
• css_capreset <player|steamid|target> (admin command)
  • Resets cap progress for selected player/target.
  • Supports SteamID and target groups.
  • Persists reset in DB.

3) One-time cap reached notification

• Added one-time message when player reaches cap.
• Configurable via:
  • NotifyOnceOnReached
  • ReachedCapMessage

4) Localized messages support for cap

• Added config toggle:
  • UseLocalizedMessages = true
• Added language keys:
  • cap_reached
  • cap_status
  • cap_disabled
  • cap_reset_success
• Added new Store/lang/bg.json.
• Updated all existing language files with new keys.

5) DB/player-load parsing fix

• Fixed parsing error:
  • Error parsing column ... DailyGameplayCreditsWindowStart=... - Object
• LoadPlayer now reads window start as formatted SQL text and parses safely in C#.
• Prevents load failure/retry loop for affected players.

Config updates

Commands

• CapStatus = [ "capstatus" ]
• CapReset = [ "capreset" ]

Permissions

• CapReset = "@css/root" (default)

Daily cap extra options

• UseLocalizedMessages
• NotifyOnceOnReached
• StatusMessage
• DisabledStatusMessage
• ResetSuccessMessage

Notes

• This PR does not modify store prices/items behavior.
• Model resource warnings (missing models) are unrelated to this change.

Testing

• Project builds successfully.
• Login/load issue related to DailyGameplayCreditsWindowStart parsing resolved.
• capstatus and capreset commands verified.
• Daily cap logic verified (including partial reward at cap boundary).

@JerryBorisov
I thought UseLocalizedMessages is unnecessary. Can you test it last version, so i can merge it?
